Comprehensive research of the effect of potassium and sodium nitrates on arsenopyrite in a intermediate product of enrichment

The object of the research was the intermediate product of ore enrichment from the mining and processing plant “Solnechny”, which is a polymineral raw material. The problem of removal of arsenopyrite and arsenic compounds and obtaining pure tin from this intermediate product of beneficiation is acute. Previously, the interaction of arsenopyrite with potassium and sodium nitrates was modeled in the program complex Thermo-Calc and the optimal composition and ratio of these nitrates for the qualitative course of the impact reaction on arsenopyrite were revealed. An alternative method of arsenic concentration reduction in polymineral raw materials was proposed. Laboratory studies of the effect of potassium nitrate and sodium nitrate on arsenopyrite were carried out in order to verify the results of computer modeling: thermogravimetric (TG) and differential thermal analysis (DTA). The experiment on influence of potassium and sodium nitrate mixture confirmed the data of thermodynamic modeling, but also revealed new compounds formed during the experiment. The elemental composition was determined by micro-X-ray spectral analysis method, and then the mineralogical composition of the original milled beneficiation intermediate product and the intermediate product with the addition of potassium and sodium nitrate was analyzed, and the compositions were analyzed after heat treatment at 700 ℃.
