Depressors definition of depressors by Medical dictionary. Early research work carried out some 12 years ago by the Department of Mineral Processing at the Faculty of Mining and Geology, Belgrade University, had as its objective the replacement of ZnS[O.sub.4] with another, more efficient modifier which could offer, apart from successful depression of sphalerite, a lower depressor
Mineral processing; Depressants Mining. Depressants. Depressants make it possible to increase final recovery consistently without sacrificing concentrate grade. They can either depress the effect of hydrophobic gangue minerals in the ore that would otherwise report with the froth along with the desired mineral, or hold down the desired mineral

A series of metallic-starch complex (MSC) solutions, synthesized by mixing relevant metallic ionic solutions with the caustic starch solution, were used as the flotation depressants to investigate their depressing effects on hematite ore. The MSC is a nano-sized colloidal complex which is configured by hydrophilic metallic hydroxide as the colloidal nucleus on which starch and hydroxyl complex
Sep 01, 2003· Mineral processing and oxide ores. 1. Introduction Studies of adsorption mechanisms of organic depressors, accomplished by Liu et al. (1994), have showed that the separation of minerals, by flotation, using polysaccharides, the hydroxyl groups at the surface of oxidized minerals can either accept or donate protons;
This paper presents the results of the examination of depressing effect of cyanide salts type reagents (NaCN, K3[Fe(CN)6] and K4[Fe(CN)6]), as well as ferrous/ferric salts (FeSO4 and Fe2(SO4)3) on the floatability of pyrite in the presence of xanthate as collector. The examinations show that all tested depressants reduce the collection ability of pyrite with K-butyl xanthate (KBX).

in certain mineral processing operations. In this communication we describe the successful use of a cationic derivative of guar gum as a gangue depressor in the flotation of zinc sulphide ore ( sphalerite ) from the Rajpura Dariba Mines of M/s Hindustan Zinc Ltd., Udaipur, India. EXPERIMENTAL PROCEDURE Material and method :
Depressants comprising one or more types of polysaccharides comprising one or more types of pentosan units are provided. Also disclosed are processes for enriching a desired mineral from an ore comprising the desired mineral and gangue, wherein the process comprises carrying out a flotation process in the presence of one or more collecting agents and one or more of the depressants.
Multiphase systems are important in minerals processing, and usually include solid–solid and solid–fluid systems, such as in wet grinding, flotation, dewatering, and magnetic separation, among several other unit operations. In this paper, the current trends in the process system engineering tasks of modeling, design, and optimization in multiphase systems, are analyzed.
