Furnace guy is here

[Baghban]

Hello everyone
I'm baghban from Iran (we are not with IRI regime and we are not all Muslim )
.
I am a slag recycler and work with a big rotary furnace. It's about five years that I know you're forum and learned a lot from it.
By the way I'm here to continue my journey in recycling world with you all.
I work on copper cell now and seeking for good advice .

What is a slug recycling?
I assume it is not snails

There are many discussions on Copper cells here, just search the forum.

Here are some links well worth a study:

We ask our new members to do 3 things.
1. Read C.M. Hokes book on refining jewelers scrap, it gives an easy introduction to the most important chemistry regarding refining.
It is free here on the forum: https://goldrefiningforum.com/phpBB3/viewtopic.php?f=54&t=19798
2. Then read the safety section of the forum: https://goldrefiningforum.com/forums/safety.47/
3. And then read about "Dealing with waste" in the forum: https://goldrefiningforum.com/threads/dealing-with-waste.10539/

Sorry for spelling mistake. I mean slag recycling. Slag of our old cupellation furnace that is produced long time ago by my father.
It's contain PbO and PM's in the texture of base metal silicates.
Our feed crush and grind at the beginning and the will process by jig machine and at the end jig concentrate will go to furnace.
.
I read hooks book and other forums in the past. But I will readem again.

Aah the dreaded spelling mistakes.
All good.
Are you using Copper as collector metal since you are talking about an electrolytic cell?

Hello @Baghban, welcome to the forum.

I like, and appreciate, your posting of a photo of your rotary furnace working. That is probably the smallest rotary I have ever seen. I like your placement of a refractory elbow to direct the discharge flame up. I do notice the discharge of glowing particles coming out the top of the elbow. What are you melting in the furnace? More details may lead to interesting discussion.

Again, welcome.

Given that your feed is litharge, I am curious if you have the ability to check your (or possibly your employees) lead levels in their blood. Is that exhaust, and the n95 mask you wear effective enough to keep lead out of your lungs?

Also, how many pound charge does that furnace take? Do you pelletize your charge or just dump it in?

Thank you for sharing.

Actually I recycle slag that belong to recycling of anode slim smelting slag )).
My father bought this slag from anode slime refiner long time ago and they are like litharge but have sulfide and copper and PM's. And we callem "metalloid". He refinedem and their slag have palladium and copper. So I started to recycling after my father's death. Actually I have two big problem.
First one is that is deliver lead- copper alloy from rotary and for oxidizing copper consume lots of lead.so I have to deal with copper electrorefining cell
Second is I don't know how to refine that "metalloid"

We have 1ton and 150 kg furnace. This is our little one. Glowing particles are coal that I charged before photo be take.

Second is I don't know how to refine that "metalloid"

The first task is to reduce these metalloids so they collect in the metallic fraction and not in the slag. You can accomplish this reduction in the furnace. Your furnace needs to burn a reducing flame and your fluxes need to reduce any metals you want to collect when you pour.

Do you have any lab capabilities to determine what metals are in the slags you are trying to recover and the quantities?

We use great axial fan for ventilation and N99 mask and drinking milk. I didn't check lead level in our blood it's a little scary .
We charge our 1 ton furnace about 350 and little one is for our test. About 60

Feed dump to furnace and it's one of our hard work.

I tested it by coal reduction but hasn't good effect. It makes sense to convert sulfide to sulfate but exactly how.
I didn't tes them by xrf or icp but they have about 5 gram pd and 10 au per tone as my father said.
The PM's mostly complexed with heavy phase that means lead and litharge phase.

Check out this thread about smelting, it discusses different flame types and properties of different flux blends. The smelting is in the library but you can link it from HERE

One of the best threads Ive ever read. Thank you thank you thank you. It was very very useful and complete

Welcome to this Forum Baghban. I see you have a wonderful rotaory Furnace. but that type of Furnace is normally used as an Oxidising Furnace by the colour
of the out going Flame it is definately bright Orange meaning to much oxygen being used. A reducing flame is usually Blue in colour. Try this by adjusting
an Oxy-acetalyne Torch, you will only be able weld with a Reducing Flame. The same will happen in a Furnace. What you should be using is a Muffel Furnace.
I once processed a 60 ton slag heap from a company that recoverd Silver from the Bearings off Scrap Jet engines. The reducing agent for your Slag will be
powdered Charcoul mixed in will the crushed Slag, then You also have to use a Slag Thinning addetive

Instead of using Coal as a reducing agent. You Should Use Coke, which the Charcoal make from Coal.

Where does this slag come from? you should not be using Lead in your process!

I think you are wrong, oxidizing flame is orange due to the amount of Carbon left in it.

Coke is prosessed Coal, basically pyrolized Coal.
Charcoal is carbonised wood.

Edit for spelling.
