In order to have a preliminary idea about the metallurgical performance of the samples, some scoping tests have to be performed. They can be carried out in the prospective mine site and/or special metallurgical laboratory. The final election is based on the equipment availability and gold mineralization. Test to be done include concentration by gravity, flotation and leaching.
Rotary Sampler Splitter
It is a good practice to test several samples or composites. The sample preparation must be done under the following considerations:
- Combine the samples according to the geologist indications
- The sample has to be crushed to 100% passing 10 mesh
- Split the sample in one and/or two kilos charges
- Take samples for head analysis and perform assays for gold and silver.
- Other elements can be detected by ICP analysis
