    gold ore extracted from mines in the earth contains a significant amount of impurities, including traces of other metals. In order to separate the gold from other metals, chemicals such as cyanide solution or mercury are introduced to the gold. this process causes the gold to coagulate, and form nuggets and clumps of gold.vms ore-forming fluids are acidic, reduced, chloride solutions in which metals were transported mainly as chloride complexes .before the discovery of black smokers, temperatures of the ore fluids were estimated from rare fluid inclusion data and sulfur isotope fractionation between sulfide mineral pairs. pH values about unit less than neutral were determined

  • Artisanal And Small Scale Gold Mining Without Mercury

    flotation is usually used by large scale miners but can also be applied in small scale operations. It is a process that works best for processing complex ore types, especially ores that are difficult to process using gravity methods. In flotation, a mixture of slurry and frothing agents are added into a flotation machine.We process black sands. due to the heavy iron content of black sands, most processors, smelters and refineries are unable to process them. We have a unique chemistry that allows us to aggressively process precious metals at mesh and below in less than one hour, so we can effectively leach black sands without dissolving the majority of their iron content.
