Technological Processes of Receiving Metals in The Conditions of Moderate Temperatures

Abstract

In article questions of physical and chemical transformations of starting materials at their heating in metallurgical furnaces are considered. It first of all moisture evaporation, dissociation of the difficult connections, oxidizing and recovery processes, formation of fusible eutectics. An attention to interaction of oxides and sulfides with formation of the new connections having smaller melting point than initial components. It is shown that these connections are the beginning of formation of melts and actually define thermodynamics and kinetics of all process. Transition of firm components of fusion mixture to flux has a great influence on technological indicators of smelting of metal. Considering it, the research on establishment was conducted began courses of these of reaction and a possibility of determination of this criterion without direct the made experiments

Flocculation of Sulfide Minerals with a Mixture of Potassium Xanthate Butyl and Water-Soluble Polymer

“…The phenomenon of the flocculation of minerals by water-soluble polymers has been studied by several researchers [11][12][13][14][15][16]. Most of them believe that the effect of organic flocculants is associated with the following phenomena:…”

Development of Resource-Based Technology for Production of Blue Vitriol From Industrial Products

“…The study on the use of copper smelting dust as neutralization of spent electrolytes requires solving the following task [5][6][7]:…”

Developing ways to reduce the consumption of reagent collectors during the flotation of gold-containing ores

“…According to Patent [37], the combined use of petrochemical residue (KOH-92) and PBX reagents leads to an increase in gold recovery of 4.9% and a reduction in flotation time compared to the flotation of gold ore from the Nejdanin mine with PBX alone. The results of using a mixture of PBX and isobutyl dithiophosphate (DTF) with isopropyl-ONmethylthiourea to increase the selective flotation carried out in the monomineral fraction of pyrite and chalcopyrite [38] have been described.…”
