Flotation separation performance of malachite from calcite

2021-1-15  In the flotation of malachite, the most widely used method is to use xanthate collectors to float malachite minerals in the presence of sulfidizing reagents, viz. sulfidization flotation method, in which, Na 2 S or (NH 4) 2 S is usually used as a sulfidizing reagent to activate malachite, and then to promote its recovery,, .

Minerals Free Full-Text Floc-Flotation of Malachite

Malachite fines are easily produced in the grinding process, leading to low malachite flotation recovery. Floc-flotation of malachite fines with an octyl hydroxamate and

Sulfidization flotation performance of malachite in the

2019-3-1  The effect of calcite on malachite sulfidization flotation was investigated by micro-flotation tests, adsorption, sedimentation and zeta potential test. The micro-flotation results showed that the finer the calcite particles size is, the lower the malachite recovery will be in the sulfidization flotation of malachite at around pH 9.5.

Flotation Behavior of Malachite Using Hydrophobic Talc

In this study, the flotation behavior of malachite was investigated using hydrophobic talc nanoparticles (TNs) as collectors. To improve the floatability of TN-deposited malachite, various experimental parameters were systematically investigated. We found that the floatability sharply increased as the size of the TNs decreased.

An evaluation of hydroxamate collectors for malachite

2017-8-7  Flotation experiments were conducted on a synthetic malachite ore prepared by mixing 10 g malachite with 90 g quartz. All flotation tests were carried out using a 1.5 L Denver flotation cell operating at 1200 rpm with an air flow rate of 5.6 L min −1. For each test, a fresh batch of ore was mixed with tap water in the flotation cell, with the water level adjusted to a set height.

Enhanced sulfidation xanthate flotation of malachite using

2017-5-18  With NaBX as the collector, malachite floatability was weak without sulfidation prior to flotation, and the flotation recoveries of malachite were 20.42% at 2 × 10 −5 mol/L concentration of

Copper sulfide species formed on malachite surfaces in

Sulfidization is a critical stage for the sulfidization xanthate flotation of malachite. Malachite yields optimal flotation performance around pH 9.5 with Na 2 S as sulfidizing agent [6]. Na 2 S
