The most important economic copper minerals are chalcopy-rite, chalcocite, bornite and covellite. Table 12.1 lists the copper minerals of economic value. Copper sulfide ores, where the pyrite content can vary from 10% to 90%. The predominant sulfide mineral in this

Handbook of Flotation Reagents: Chemistry, Theory and Practice is a condensed form of the fundamental knowledge of chemical reagents commonly used in flotation and is addressed to the researchers and plant metallurgists who employ these reagents. This book consists of three distinct parts: part 1 provides detailed description of the chemistry

15.1.1 Hydrothermal Vein Deposits. The copper lead-zinc vein deposits are usually characterized by coarse-grained banded to massive aggregates of pyrite, galena, sphalerite and chalcopyrite. The bulk mineralogy is quite similar to that of strata-bound sulfide deposits, except that galena tends to be much more abundant in the vein deposit

Flowsheets may be drawn by hand at preliminary stages of a project, but with process simulators and CAD software packages, it is a simple matter to develop flowsheets with a consistent set of symbols for equipment, piping, and operating conditions contained in software packages. There is no generally accepted set of standards, although attempts have been made with little success

Feb 15, 2021 Sulfide ores contain copper-iron sulfides and nickel iron sulfides. These sulfide ores produce high grade nickel. Processing of sulfide ores occurs in reverberatory or flash-smelting furnaces and horizontal convertors. Copper and nickel sulfide separation happen via crystallization, grinding and froth flotation

Sodium hydrogensulfide is flake-shaped as a solid and available as a lye in liquid form. The scales show up through an unpleasant odor. The product has good properties in solubility in water. In the ore flotation, sodium hydrogen sulfide is used as an auxiliary. The flotation is a chemical separation process in which fine-grained solids such as

Jun 10, 2019 Ore properties: Copper, lead, zinc and silver minerals were mainly associated with sulfide ore and oxidation ore. Xinhai solution: Three-stage crushing with single closed-circuit stage – two-stage grinding – bulk and separating flotation – two stage dewatering process. The recovery rate of copper ore reached 83.30%. 2

What is claimed is: 1. A method for beneficiation of a mineral sulfide-containing material by air-injection froth flotation in the presence of a collector, the method comprising: a) providing an aqueous slurry of the mineral sulfide-containing material; b) adding a selective collector to the slurry in an amount less than about 100 g/ton of the mineral sulfide-containing material, the collector

A new reagent system, developed by Versitech, Inc., with assistance from DOE's Inventions and Innovation Program, recovers copper minerals at a much lower pH than conventional reagents and avoids floating pyrite. The process reduces or even eliminates both the lime used in copper flotation and the accompanying carbon dioxide

This invention is directed to the use of non-sulfur containing compounds as collectors in the froth flotation of certain mineral sulfide and metallic compounds. These non-sulfur-containing compounds may be from natural sources, such as vegetable oils, or synthesized commercial sources. These non-sulfide collectors can be used singularly, in combinations, and in mixtures with known commercial

An improved method for recovering lead sulfides from a mineral deposits. Pulverized mineral deposit material is mixed with water, agitated with pH adjustment from about 8 to about 10.5 to form a slurry. Rapeseed oil is added to the conditioned slurry to render the surface of the lead sulfide particles hydrophobic. After agitating and adding a frothing agent, air bubbles are injected into the

Our alternatives have proven performance in the flotation of copper ores, polymetalic ores and gold associated to sulfides. HOSTAFLOT collectors are formulated to achieve the best possible recovery and selectivity when needed. Our solutions encompass the flotation of
