 I asked the same a couple weeks ago. Not much information came my way, hope you have better luck. There's lots of information out there, enough for a good idea, but seems incomplete.

How much material do you want to leach at a time? Do you have an idea of the gold content and the mineralogy of the material to be leached?

there are several tons of ore to be processed. each batch would have to be large enough to be economical but small enough to be efficient. gold content im not sure but it is rich and the ore has freemilling gold but the area it was taken from is known for the micron gold. i need to test it to know for sure and i wont get out there for a few months yet. i know that there are many factors like the type of ore but im trying to get as much info as i can before i go in the field.

I am currently leaching in a non cyanide method and am starting to make leaching kits that can handle 300 to 400 lbs of ore. I would be glade to help answer any questions.

I have worked with quite a few of the available leach chemistries and am happy to help but some basic understanding of the ore you have to handle will be real handy. Many of the alternatives to cyanide really work better on a concentrated feed if dealing with lower grade ore. Its both an economy thing and a chemistry thing.
When you said you were not interested in dealing with concentrates I took that to mean you wanted to do bulk leaches or heap leach like thousands of tonnes. Reading your follow up posts I see the potential for vat or tank/trickle leaching IF the ore properties and economics will allow.

Angus MacKirk Mining sells a small leaching sytem. Suposed to be able to get all the chemicals needed from over the counter type stores. Might be worth looking into.
