Abstract

The invention discloses an arsenic removal and carbon removal agent. Raw materials comprise, by weight, 50-85 parts of pypocholoride, 10-40 parts of calcium peroxide and 5-10 parts of barium hydroxide. The agent can be used by being mixed with sodium cyanide, environment-friendly agents and other gold leaching agents. For arsenic and carbon containing gold ore, the leaching efficiency is improvedto different degrees, and meanwhile agent consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of gold production, and is an effective method for treating refractory gold ore, in particular to an agent for removing arsenic and carbon. Background technique [0002] Arsenic-containing gold ores are refractory ores. At present, there is no good treatment method for this kind of ores in the world. The conventional leaching costs are high and the leaching rate is low. Arsenopyrite, realgar and orpiment are the main arsenic minerals in common arsenic-containing gold ores, and gold often coexists closely with them and is wrapped in them. A thin film is formed on the surface of the particle to prevent the leaching of gold, resulting in a significant decrease in the leaching rate. [0003] Carbonaceous gold ore refers to a type of gold ore containing amorphous carbon, graphite, lignite or organic matter with a high carbon-to-hydrogen ratio. Carbonaceous matter in carbonaceous gold mines can be divided into e...
