Gold-arsenic sulfide mineralization of the Kayancha area, Gorny Altai
Руды и металлы, 2023 Gold-arsenic sulfide type mineralization has first been revealed for the Gorny Altai region. The mineralized zones associate with lamprophyre dikes and are controlled by steeply dipping faults transecting the Vendian-Cambrian terrigenous-carbonate ...

Studies on Nickel and Cobalt in Arsenopyrites. I. Estimation and Determination of Cobalt in Some Arsenopyrites [PDF]
Bulletin of the Chemical Society of Japan, 1943 Abstract Nitroso-R-salt method has been investigated for the purpose of determining a minute quantity of cobalt in minerals. In some previous papers it was reported that the method is very satisfactory for determining cobalt in plants, soils and animal nutritions.

Engineering Reports, Volume 8, Issue 8, August 2026.A local adsorbent, synthesized via magnetization and functionalization of nanosilica from rice husk, was applied to eliminate As5+ from gold mining wastewater sample. Adsorbent was characterized using BET, FTIR, SEM and XRD and was proved to be effective and suitable for As5+ removal from gold mining wastewater.
