Mining

JOHE provides natural solutions for complex problems in mining and extractive metallurgy. We have a broad range of technologies that dramatically improve the efficiency and effectiveness of industrial processes — including the BIOX® gold process, flotation, leaching and clay dispersion.

The BIOX® gold process has revolutionized the treatment of refractory gold ores that were once uneconomical to pursue.

Aurumer B-Ox further improves this process by dramatically increasing gold recovery in the counter-current decantation circuit. Aurumer B-Ox has been shown to raise overall gold recovery by 2–3%, adding significant value to the process.

Our product has become the industry standard for depressing calcite in fluorite flotation processes, and is the leading specialty reagent used worldwide to produce chemical-grade fluorspar. When elemental sulphur is present in leaching it can coat zinc particles, limiting efficiency; our zinc reagents are excellent sulphur-dispersing agents that greatly improve leaching efficiency.

Tupasol ATO and Guarani P3M — tannic extracts ideal for the mining industry — dissolve easily in cold water and are supplied as powder, in 25 kg bags or 1000 kg big bags.
