CLS 20, 21 and 22 were developed in the 1970s designed to work at room temperature (60 – 80° F.) It has become increasingly difficult to ship chemicals, especially internationally. Therefore, we have ceased to mix these CLSes but offer the formulas for purchase so that the necessary chemicals can be obtained locally and mixed in-house by the consumer. Our leach products are acidic leaches, that can be re-used, getting better results in most cases than single compound leaches. Any complex ore can be tested with CLS-20, 21, and 22. Each leach has different oxidizers and leaching components. One of these combinations may work better on your ore. They are not for concentrates.
Concentrates should be tested with CLS-25, a gold leach. If you are interested in purchasing the formulas, please contact us.
NOTE: IT IS POSSIBLE TO LEACH TOO LONG. ALL LEACHES KNOWN WILL BEGIN TO PRECIPITATE GOLD BACK INTO THE ORE AT SOME POINT. This usually doesn’t happen for as many as 72 hours, but in some ores it can happen in a few hours. WATCH FOR IT!
We are phasing out 1 lb containers due to high packing & shipping costs! Limited quantities available.
CLS 26P is our leaching compound for the platinum group metals in ores or catalytic converter material. As with all our leaching compounds, the solutions are re-usable by ‘strengthening’ with additional powder.
