The sulfidisation, acidification, recycle and thickening (SART) process is currently being used at NewcrestÆs Telfer Gold Mine to recover cyanide and copper from the cyanidation tails of the pyrite concentrate carbon-in-leach (CIL) process. While the process has been effective at attaining high recoveries of cyanide and copper, the Telfer …
The pyrite removal step (a) may include thickening and/or filtering the pyrite-containing material stream and de-watering the material and forming a pyrite-containing concentrate. ... The second product is a pyrite concentrate that can be used beneficially in a downstream heap leaching method for a copper-containing material. In this ...

The barren washed tails are floated to recover a pyrite/elemental sulfur concentrate. The concentrate is oxidized at 225°C to produce a final solution containing acid and ferric sulfate. ... The flowsheet (see Fig. 7) comprised fine grinding of the concentrate, pressure leaching, thickening and filtration, copper SX/EW, with a bleed …
The annual metal outputs of lead and zinc are more than 40,000 tons, with 17 tons of silver recovered annually from the lead concentrate. In addition, the design capacity of sulfur (pyrite) concentrate is more than 60,000 tons annually, with the output depending on market conditions (Gong, 2007).

Copper Concentrate Thickening and Filtering. The final cleaned flotation concentrate flows or is pumped to a Spiral Rake Thickener. A Adjustable Stroke Diaphragm Pump, mounted on the thickener superstructure, meters the thickened concentrate to the Disc Filter. The Thickeners are often used to store concentrates for …
thickening and filtration has raised steeply the yield ©f pyrite concentrate, which in turn made it possible to con- vert the Combine's sulfuric acid shops to the processing of a cheaper and qualitatively better raw material and to dis- continue the importing of pyrite from other enterprises. The economic effect yielded by the conduct of these

Pyrite thickening and pressure filtration will be conducted to produce a pyrite concentrate filter cake or discharging to tailings. The sulphide tailings will be passed through magnetic separation to recover …
The pyrite concentrate is treated in the CIL. Copper concentrate is stockpiled and sold to a smelter for further processing. In recent times, as the depth of the pit has increased the copper head grade has also increased, to the point where the ore was becoming uneconomical to treat. ... Recycle and Thickening (SART) process was …

The processing plant will be designed to produce a bulk copper concentrate for sale and pyrite concentrate to be stored for possible treatment to recover the contained gold and generate sulphuric …
The clean pyrite concentrate was obtained on a vibrating table from the underflow of the Chinchan tailings dam and classified in 100, 140, and 200 mesh (group …
Mean elemental weight fractions of pyrite concentrate powder ball milled for 7 min determined using semi-quantitative WD-XRF data, and standard deviations from five repeat samples. The Kα peak of oxygen was visible but O was excluded from the analysis due to the lack of accuracy for this element.
A copper-pyrite mill in Canada uses the 12-cell No. 21 "Sub-A" Flotation Machine, shown above, for roughing, and a 2-cell No. 21 "Sub-A" Flotation Machine for cleaning to produce a fairly coarse pyrite …
While the copper minerals, separated in this phase, constitute the copper concentrate, pyrite minerals constitute the pyrite concentrate. During the pyrite concentrate oxidizing roast, first SO2 then H2SO4 (sulphuric acid) is produced . The released iron-oxide is used in the cement and iron-steel industries. Our annual capacity is 400,000 mt ...

1. The Characteristics of Gold-Pyrite Ore. When determining the beneficiation process of gold-pyrite ore, it is necessary to understand the material composition of the ore and the symbiotic relationship of gold in the pyrite. In general, the mineral types of this ore are simple and the content of pyrite is high.
The flowsheet is designed for the production of a high grade copper concentrate followed by the production of a clean pyrite concentrate for further treatment to recover the gold values. ... The filtering characteristics and tonnage will determine if direct filtering of the concentrates can be used or if thickening prior to filtering must be used.
