Using the mathematical planning of the experiment by the method of Latin squares, we optimize the adsorption conditions for Bi(III) from dilute aqueous solutions and its desorption from the surface of silica gel L100/250. It is found that the maximum degree of adsorption (95–98%) is reached at pH 4.5, near the zero-charge point of silica gel and …

Abstract. The ore from Baiyinchagan mine is typical increasingly refractory as the mine get deeper, especially the increasing lead and zinc contents, which not only detrimentally affects the product quality of copper concentrate, but also results in the loss of lead and zinc resources In order to solve the problem, two routes were conducted: first, …

In this Special Issue, recent advances in copper ore processing and extraction are discussed, focusing on: innovations in hydrometallurgical, pyrometallurgical, electrometallurgical, and pre-concentration technologies; improving …

Bismuth leaching efficiency increased linearly with reaction temperature, from 57% at room temperature to 92% at 70 °C when other operational parameters were kept constant i.e., 100 g/L H 2 SO 4, 60 g/L NaCl and 120 min. Reaction temperature had negligible effect on the leaching behavior of Pb and Ag.

that although bismuth forms its own minerals, it is mainly extracted as a byproduct in the processing of polymetallic ores and concentrates containing tenths and hundredths of a percent of this metal [2]. There is a need to control the concentration of bismuth in ores and concentrates, end products, wastewater, and envi-ronmental objects.
