This is very hard to explain, but what the guys here are telling you is for your own good, ore is complicated and can be dangerous to try to manipulate, it can be a complete science of its own, and gold or other metal extraction from millions of different types of ore is another science in itself.
Ore can be many different compounds, if it contains free gold metal, the gold can be mechanically separated.
In fact since time began not much gold has been pulled from the earth, and what has been most all of it has been removed as free gold, not gold locked up in a chemical bond with ore and leached free from the grips of the chemical bonds.
If the gold is locked up chemically, say as a sulfide for example or one of the many other compounds (there are many), it will not be set free easily, sulfides are common but they are not the only type of ores, basically, to try and describe this somewhat, metals when dissolved with acids or acidic compounds, or basic compounds we get salts of the metals and the acids, ore can be many different metals and acids or compounds, salts of metals and acids, which form a type of salt or compound of these metals and acids, they can be formed from high temperatures or pressures in the earth, or in a volcano... for example with acidic sulfur compounds these can include metals or several combinations of metals, or metalloids, along with gangue materials like silicates or many other non metals, some of these can produce strong poisons when heated or treated chemically basically the chemistry make up of ores are very complex, not all ore is the same, even in one mountain there can be several different types of ore, and even ore of the mountain of the same mine can have become chemically changed by time or oxidation even changing the chemical makeup of that one type of ore...
Many of the ores that do contain gold also contain deadly substances when roasted or chemically treated, can be very deadly to deal with.
Every ore is different, not every ore will react the same to the same pretreatment, or leach, or acid or base, or other processes, each has its own chemical make up and each will react differently when you try to treat it thermally or chemically.
Like in any chemistry to get results you need to understand the different chemicals or compounds you are mixing, example say I wish to make table salt, I have to know what chemicals I am using to make it, here in my example I choose Hydrochloric acid and sodium (metal) hydroxide and mix these to pH 7, but if I wanted to make table salt, and I use a known acid like HCl, and threw in an unknown compound like or no telling what, I would get no telling what, and the results would be no telling what, the reaction would be foolish at beat and very likely very dangerous, I would just be making a dangerous solution, and produce no telling what kinds of deadly gases from the reaction, I cannot expect to do chemistry with an unknown ore, and some known acids and produce gold from the ore, or do chemistry mixing things willy-nilly and expect some kind of outcome, at most I could hope to not kill myself, by the many different chemical concoctions I would be producing.
Trying this type of chemistry blindly would be fruitless and just plain stupid.
You need to know what kind of ore or concentrates you are dealing with, what they are composed of, and how they will react to different treatments, heat, acids or any of the many processes used...
You also need to study how others have found the best approach to dealing with that type of ore, or you may have to experiment to find the best approach, in your special case, education is where you will learn, you will need to educate your self about the ore you have, and how to best deal with it, educate yourself on the dangers, educate yourself on recovery methods used, or educate yourself on how to develop one that may work to free the gold in your case.
Mining free gold is one thing, breaking the chemical bonds of gold from ore and to recover that gold is a totally different thing.
I am sure sending man to the moon was simple (for the scientists who did it), shoot him up in a rocket at the right angle so he will hit the moon, mining is similar it is a simple thing, until you begin to learn more about It, and how complicated it actually is...
I am tired and can not explain this well, I hope you get the idea.
Listen to the advice, these guys have spent some time studying and know what they are talking about, and at least enough to help you, it is not as simple as you think it is, that is unless the gold in your ore is free gold, and your concentrate are fairly pure concentrated gold, then you just need to lean to concentrate it mechanically, if it needs leaching you will most likely need professional help or do a ton of study to learn to become a scientist and chemist in the art of gold ores...
Experimenting with acids and ores (especially unknown ore) without educating yourself makes as much sense and playing Russian roulette, and the outcome likely may not be too much different.
This is hard to explain, and I do not think it can be explained (at least by me) in one or a hundred posts, you really will need to educate your self, to understand what we are all trying to say, educate yourself on playing this Russian roulette before you load the gun and pull the trigger...
