Separation practice of copper arsenic sulfide ore

Separation practice of copper arsenic sulfide ore. The separation of copper and arsenic is mainly to solve the separation problem of copper minerals and arsenopyrite, which can be summarized as follows: (1) Highly selective collector. It is very important to enlarge the separation of the two minerals by using selective collectors. For example, the combination of xanthate and black medicine of

Minerals Free Full-Text Release Behaviors of Arsenic

In addition, a vacuum separation method was proposed to recover elemental sulfur, arsenic sulfide and arsenic trioxide from ASS in a step by step fashion . The wet method involves treatment by acid leaching or salt immersion, and the arsenic product is separated and further recovered. This technology does not produce dust, and has the advantages of low energy consumption, low pollution, high

How Does Arsenic Get into the Groundwater? Arsenic

In these situations, arsenic has to be associated with a reduced chemical, like sulfide. Many arsenic-containing minerals also contain sulfide. In the presence of oxygen, bacteria can oxidize sulfides instead of organic carbon to generate energy (for these bacteria, reduced sulfur is “food”). Once the sulfide is oxidized to sulfate, it is soluble in water, and releases the arsenic. This is

Arsenic sequestration in pyrite and greigite in the buried

01/09/2020· Instead of being adsorbed or structurally incorporated, arsenic formed distinct arsenic sulfide phase in the greigite-enriched sediments, which was analogous to realgar. The transfer of As from iron sulfides to ferrihydrite temporarily retarded As release into groundwater under slightly oxic groundwater conditions. However, the reductive dissolution of ferrihydrite and potential subsequent As

Realgar, α-As 4 S 4, is an arsenic sulfide mineral, also known as "ruby sulphur" or "ruby of arsenic". It is a soft, sectile mineral occurring in monoclinic crystals, or in granular, compact, or powdery form, often in association with the related mineral, orpiment (As 2 S 3). It is orange-red in color, melts at 320 °C, and burns with a bluish flame releasing fumes of arsenic and sulfur
