Right here we go this is going to be my written method statement, i believe evrthing should have a plan of attack also enabling you find any problems before they occur, now i am no scientist nor chemist, i im only getting the grasp of what certain chemicals react with certain metals, there is lots.
i will complete this in 4 sections:-
1 will be ram/memory sticks ,
2 will be ceramic cpu ,
3 will ceramic cpu lids and other gold plated metals like some pins i have, and
4 a final refine tho everything stated here would of already been refined once,
there will eventually be a
5 of which i have not researched enough and this will be all my flat packs off the ram and the left over cpu ceramics( burned/crushed/process )
1:- memory sticks / ram ( Depopulating )
Right first of im going to get one of my 5 ltr buckets and a drill bit and get some 4-5mm holes in the bottom of the bucket also about 2 inches up the side of the bucket ( iv never seen this but sounds brilliant) i will then place this bucket inside of another that is the same size thus making it nice and snug, i will then put ( maybe edit ) 4.5kg 9lb or even half again into the bucket.
in a coffee jug i have i will bring to the boil some 36% HLC( hydrochloric acid ) when warm i will empty the contents into the buckets with the ram inside , covering all the material by a inch or so
i will put lid on and as the buckets are made to fit snugly then 1 lid should technically cover 2 buckets.
put in safe warm place and wait.
this process i believe dissolves tin/tin solder ( not silver ) allowing all components to fall off remember agitation is vital to this process to help dislodge the components.
when you see all the components have fallen off, pull up the first bucket allowing all the (hlc) to drain off and strait it another bucket of water to rinse.
gradually work through your boards rinsing them making sure all tin has gone and put them some where to drain /dry, or make a pile on a towel.
you result will be 2 piles, 1 pile of clean ram boards and one pile of clean components ic/flatpack ect.
either reuse your hlc to leach again or simply filter and leave the lid off and this can be reused as normal hlc ( i might need correcting on this )
(AP) Acid peroxide (3 parts hydrochloric acid ( HLC ) 1 part Hydrogen peroxide ( H202 )
with my nice clean boards im going to use the same bucket system as i did before, i will put around 2.5 lb of my ram boards in the buckets i will ad (HLC) in 500ml increments until the ram is covered i will then add 1 quarter of (H202) to whatever the amount of (hlc) there was.
again i will heat my (HLC)before i add it , again agitation is vital at this process, i will just simply keep an eye on it from here adding (H202) when i start to loose that transparent emerald green color, when i feel all the foils have been taken off i will proceed with filtering the foils out.
when i am at the stage where my memory is free of gold, i will again pull the first bucket containing the ram that has holes in it from the the other bucket and start to work my foils down with some tap water in a spray bottle ( i will not rinse to much as id like to keep the (AP).
i will then transfer that ram bucket to a fresh water bucket and continue to rinse.
my end result will be a pile of stripped memory, a bucket of (AP) with foils in it and sludge and fresh water bucket with foils in it and not so much sludge.
Separating foils and cleaning )
right first things first you want a is bucket a colander and 3 coffee filters and filter of your water buckets with foils, very simple pour water from the bucket into the filter leaving the foils at the bottom, add some more water to foils and agitate, and filter the water again leaving the foils in the bucket you should now have some foils in one bucket water in another and a filter with maybe some gold foils with it just put this filter into the bucket of foils for later.
now the (AP) first of filter the (AP) into a buck again with the colander a fresh bucket and 3 coffee filters, when u have filtered most of the (AP) ( again trying to leave foils and sludge in the bottom) put the filtered (AP) to one side you can use this again or get another batch on strait way adding fresh (HL)(H202) as needed.
time to start cleaning and diluting that sludge, you should have some (ap) and sludge in you bucket, add a load of water mix it about let some of the sludge( gold ) settle the filter into a waste bucket, repeat this 3 times then leaving some gold and materials at the bottom, spray your filter clean with water into the the waste until its as cleans as u can get it keeping the gold in the filter at this stage now rinse your filter in to the bucket with your gold, as it contains gold you might have filtered from the (AP).
collect all the foils together into your coffee jug and get ready for more cleaning.
now what i will do is add water to the coffee jug boil it add cold water and decant, ( i will always decant any solution through a filter) repeat this twice, i then will do exactly the same with (HLC) and add cold water and decant also leaving all the gold in the coffee mug at this point, now you should be left with some nice clean foils ready for (AR)
Dissolving gold (AR) acid ( ????) ( poor man 3 part (HLC) 1 part sodium hypchlorite) / 9 3 part (HLC) 1 part nitric acid )
Can i first add that all these process's we go through are to remove metals, metals you do not want in your gold.
now theres 2 main (AR) i know off one is hydrochloric acid and sodium hypchlorite ( blaech/clorax) ( poor mans) and hydrochloric acid and nitric acid.
i will use the nitric acid for refining my powders only, dont ask me why, it might have something to do with the fact i dont want to use a poor mans method to refine my gold, tho i have no scientific knowledge on why these 2 process are different, but thats just when im gonna roll today.
now with my foils in a coffee pot i will cover with hlc about a inch above, i will then use a pipette to add my chlorite in increments, there will a reaction starit way as you ad the chlorite and its at the end of this reaction you will add more chlorite, keep doing this until the reaction stop and the gold has gone(left base metals), and id let it sit for a hour, after which its time you can test your solution for gold
Testing for gold ( stannous chloride ) dropping your gold (SMB) ( Sodium metabisulfite or as i learnt metabisulphite )
right as far as stannous is concerned im in the unknown so i will update this, i have purchased 3-6% gold testing jewelers stannous chloride so i dont knowif the effects will be same as the powder and nor do i now the dilution ration of the sannous tho i would just water until it disolves and makes small batches at a time,
( you can make stannouse chloride ad some tin to HLC and boil you will be left with stannouse chloride in the bottom, rinse the powder keep for a rainy day
thanks GEO )
so after you gold has dissolved in (AR) its time to test for gold Take a napkin and add a drop of stannouse, then take a drop of solution and add to the napkin i believe you should have reaction thats creates a dark circle, this tests positive for gold time to filter.
now i have finer filters for this stage to take out any impurity and at this stage all equipment should be spotless.
now pour your (AR) into you filter and funnel in to a clean jar, when filtered rinse the remaining traces of gold and solids from the (AR) jug and as the contents sits in the filter your aim is to clean that filter with you spray bottle as its soaked up gold solution and gold will be trapped in any base metals the made it to the filter, after your happy its clean, you should be left with a quite clear solution, no need to test at this point.
time to drop you gold (SMB) the amount is simple if you expect 3 grams of gold from it ad that and a third so i would add about 4.5 grams of (SMB)
i will add this to the solution, stir the solution and leave to settle for however long it takes, at this stage i will test the solution every now and then with stannous and when it test negative i will know my gold has settled, i will decant solution, clean my powder a little and dry it out, store it ready to add to a bigger lot for better refining and cleaning.
2:- Ceramic cpu using (AR) Hydrochloric acid and nitric acid
Right to me this one seems so much simpler than the ram as you skip the whole (AP) process, as there less base metals to remove,
I will start buy holding a cpu ( with the lids on ) and hit them with a hammer, and lids will separate ( put them a side for plated scrap) and the put the rest of the cpu and ALL its contents into a jar. i will break my cpu into about 4 for the first run, after i am finished i will the clean them and crush them even smaller for a second gold retrieval process later on. i believe the ratio for this (Ar) is 3 parts hydrochloric to 1 part nitric acid, but i will judge the amount buy sight of the reaction.
So... cover your broken cpu with (HLC) about 10mm above then add about a 5th its volume in water (H2o) take the jug with your cpu and put it on you heat source and gently bring to gentle simmer, now with the lid on slowly start adding your nitric acid( i will use a pippet ) a reaction should take place strait away and a flume of fumes,will emerge( red/brown), again when your reaction stops then add some more nitric, at the exact point you have no reaction from the nitric, or no gold left, then you are done, let the solution cool to room temperature, and test for gold.(stannous)
if here you have added to much nitric you will have to add some urea until the reaction you see stops or add some HLC and boil down to cook out the nitric, if done properly this will not need to be done.
right the difference from the cpu and ram and this stage is we had already removed the tin /lead/silver solder from the boards where as there was still some solder on the cpu so this will have to be sorted.
get a clean jar and add some ice put a funnel and clean filter on top, now decant and filter you gold solution into the iced jug, the ice itself will help to drop lead sulphates out i believe, add all you solution dilute the remaining leftovers from the cpu and decant that as well, you will also want to clean the filter and funnel with water to ensure no gold loss. after this add about 15ml of sulfuric acid which will help drop the remaining silver from the solution( ammonia will also dissolve silver/when cleaning ),let all this sit until settled , and filter and decant again into another clean jug.
from here simply drop you gold and wash it just like in the steps before then add you dust to you collection
3:- gold plated scrap (hlc Leach/bath)
iv researched this lots and not really found all the answers what im looking for so i will attempt this i suppose in my own way,
iv 50g gold plated pins about 30g in bits of plated scarp and 16 gold plated cpu lids, i will do all this together.
i will start buy putting the scrap in to a jug covering with (HLC) and then bringing to a simmer, this im hoping will dissolve some solder and maybe help remove some foils, after this stage i wills rinse and decant everything and put all the contents including any undissolved metals into ((AR) with clorite, dissolving whatever gold is in there, to be late dropped.
im goin to stop there until i have clarified a few more points as im not sure what reactions i will defiantly get from this process, so will update soon
