Rappa Resources’ processing and recovery plant is designed to process a variety of precious metal bearing material, such as:
Woodchip, which are generated from underground mine supports which become caught up in the ore being processed. They are screened off after the milling stage of the mine operator’s processing plant;
Activated carbon, gold recovery from loaded activated carbon using different solvents;
Fine spent / contaminated carbon, which is generated when modern processing plant re-processes activated carbon for reuse. The abraded carbon grains are collected by screens or filters in the mine operator’s processing plant;
Carbon sludge;
Mill grease, which when replaced is re-processed by Rappa Resources to recover spillages of ore which has stuck to the grease;
Mill Liners, which are used to protect the mill shell used in the mine operator’s processing plant. Made of rubber or manganese steel alloys, they collect small amounts of gold or precious metals which can be liberated through the company’s processes;
Slime / Vlei material, which is generated in the vicinity of the mine operator’s processing plant and which tends to accumulate in settlement dams or vleis.
Rappa Resources is not limited to the by-products described above, and will consider all materials containing precious metals.
