Polysaccharides in flotation of sulphides. Part I. Adsorption of .

Polysaccharides were widely investigated as depressants of inherently hydrophobic minerals. They found broad applications as dispersants/depressants in the flotation of sparingly soluble salt-type minerals and as flocculants/depressants in the selective flocculation/flotation separation of fine hematite from silica. Reports.

Consequently, aside from a few fundamental principles regarding flotation and the use of reagents, it is generally agreed each ore must be considered a.

Gold Flotation Process - Froth Flotation (Sulphide & Oxide .

Let me explain with more detail about my question: We are studying to float a sulfide ore. The Ore basically contains sulphide minerals dominated by pyrite, together with ancillary marcasite and traces of copper sulphides, accounted for 5 to 7 percent by weight of the ores. These sulphide minerals were emplaced in silicate.

Froth Flotation in Saline Water - J-Stage

The flotation of Cu-Mo sulfide ores requires the use of flotation agents, which are different for the inherently .

Effects on entrainment of serpentines by hydrophobic . - (SciELO) SA

serpentines can hinder the enrichment of some metallic minerals and dilute their concentrates by entrainment during flotation. The resulting high pulp viscosities, slime coatings, and high content of dissolved ions adversely affect the flotation recoveries of copper and nickel sulphides, and high levels of MgO entrained in.

Mining Chemicals - International Mining

Jun 1, 2011 . For example, Codelco Andina and Anglo American Los Bronces are on the same mineral belt and one opposite sides of the same mountain. They both are floating similar copper sulphides yet one of them uses sodium isopropyl xanthate (SIPX) and diethyl dithiophosphate (DTP) and the other is using.

Dec 19, 2017 . The flocs formed through hydrophobic flocculation induced by potassium amyl xanthate (PAX) and kinetic energy input. The studies . Also, the floc flotation was tested on the Rey de Plata ore of Guerrero of Mexico, in which some of the metallic (Pb, Zn, Ag, Au, Cu) sulfide minerals are finely disseminated.

Greening Chilean copper mining operations through industrial .

Sawdust was used as cheap sorbent for the remediation of a diesel and oil fuel-contaminated mining soil whereas biosolids were evaluated as collectors and frothers in froth flotation of copper sulphide ores. The use of these waste materials in copper sulphide ore mining and mineral processing may have a positive.

The impact of water quality on flotation performance - SAIMM

Synopsis. Water represents 80–85% of the volume of mineral pulp processed in flotation circuits. Imperatives for a more detailed focus on circuit water quality and its control have come from increasing . combinations; organic species removal; flocculation and ... well as adsorbed layers (e.g. copper(I), calcium sulphate).

13 μm) and ultrafine (''UF” <13 μm) copper sulphide particles. Also, the comparative effect of high inten- sity conditioning (HIC), as a pre-flotation stage for the rougher flotation, was studied alone or combined with CRF. Results were evaluated through separation parameters, grade-recovery and flotation rates, especially in.
