CONCENTRATE THICKENING AND FILTERING. The cleaned antimony concentrate is pumped to a Spiral Rake Thickener to remove excess water prior to filtering. A Adjustable Stroke Diaphragm Pump meters the thickened flotation concentrate to a Disc Filter.
Concentrate grade refers to the amount of gold that can be extracted from ore through various extraction processes. In order to obtain high-grade gold concentrate, miners must consider the following three factors and the corresponding improvement mathods. 1. Raw ore quality. The first factor affecting the grade of gold concentrate is …
As sodium sulfide is easily oxidized to polysulfide and thiosulfate which have a gold leaching effect, gold would dissolve in leaching solution when extracting stibium from gold containing antimony concentrate by alkaline sulfide. Through leaching test and kinetics analysis, the decomposition regularity of sodium sulfide and leaching rate were …
The distribution of antimony in sulfide copper-zinc concentrates processing products manufactured according to a production scheme including autogenous smelting, matte conversion to blister copper, and flotation extraction of metals from slags, is evaluated. The main products concentrating antimony concern autogenous smelting …
An integrated two-stage metallurgical process has been developed to process concentrates from the Olimpiadinskoe deposit, which contain high levels of antimony and arsenic. The optimal parameters for the alkaline sulfide leaching process of the initial concentrate from the Olimpiadinskoe deposit were determined to achieve the maximum …
1. Background. Antimony is a silvery, white, brittle, crystalline solid that exhibits poor conductivity of electricity and heat. It has an atomic number of 51, an atomic weight of 122 and a density of 6.697 kg/m 3 at 26 °C. Antimony metal, also known as 'regulus', melts at 630 °C and boils at 1380 °C.Antimony and the natural sulfide of …
Antimony concentrate produced in Eti Bakir Halikoy Plant is used in many industries: as a metal alloy in the metal industry to build fire resistant materials and paint because it amplifies fragility and rigidity; to harden the lead in accumulator industry; to manufacture brake pads in automotive industry; to manufacture various products in the defence …
Acid leaching makes it possible to obtain expensive antimony trioxide directly from gold-antimony concentrates, by-passing the extraction of metallic antimony from the …
The operation of dewatering is performed in two stages. First, the bulk of the water is removed in a thickener, from which the concentrate is discharged as a thick pulp ; as a rule the underflow contains 55 to 65% of solids, while 70 to 80% of the original water is recovered in the overflow as a clear liquid. The thickened pulp is then sent to ...
