The discovery of the significance of heat on leach recoveries, triggered extensive testwork on a range of leach feed and tails samples. Pilot plant testing demonstrated that "Heated Leaching" of the CIL tails was the best process with an average recovery increase of 7.5% being achieved.

Oct 10, 2016· "The Telfer processing plant commissioned its pyrite regrind and flotation circuit in August 2012. The circuit was designed to regrind pyrite concentrate to a p80 of <30µm then float a gold and copper rich concentrate before tails from the flotation circuit fed the carbon-in-leach (CIL…

When the concentration cycle is complete, concentrates are flushed from the cone into the concentrate launder through a patented multi-port. Carbon in Leach (CIL) The tails empty to a tank and pass through a thickener before passing to the carbon in leach (CIL) tanks. Cyanide and hydrogen peroxide are added into the No1CIL tank.

The locked cycle flotation test, followed by pressure oxidation (POX) and carbon-in-leach (CIL) cyanidation of a gold-bearing sulphide concentrate, on a project-wide composite (PWC), yielded overall recoveries of 95.0% gold, 90.8% silver, 91.2% zinc, and 84.6% lead to potentially saleable products.

A double refractory gold ore contains gold particles locked in sulphides, solid-solution in arsenopyrite, and preg-robbing material such as carbonaceous matter, and so on. The diagnostic leach test (DLT) and preg-robbing (PR) approaches are widely used to investigate the occurrence and the distribution of refractory gold. DLT serves to qualitatively evaluate the gold occurrences within the ore.

Of all the methods of extracting gold & processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets. This page offers a comparative review of gold recovery ...

The mine is licensed to 7.5M t/y and treats 7.3M t/y with approximately 5-8% of the feed reporting to sulphide concentrates on regrinding and subsequent cyanide leach. The plant includes a primary crushing circuit, SABC (SAG and balls mills, with pebble crusher), flotation cells and a CIL circuit.

tails. The product from the concentrate leach circuit is processed by resin in pulp for uranium recovery, followed by neutralization, cyanidation and carbon in pulp for gold recovery. The rougher float tails may be further treated to recover gold that was not recovered in flotation, but which had been liberated from the old dumps by

ore samples crushed to -150 mm, flotation concentrate milled to -45 µm (FC), biologically oxidised flotation concentrate (BIOX® CIL feed), and tailings from the post BIOX® Carbon in Leach circuit (BIOX® CIL tails). In each case, the samples were collected and composited over a two-week period,

The main sulfides are arsenopyrite, pyrite, and pyrhottite. The ore is floated, with the flotation tails passing to a tails CIL circuit and the flotation concentrate reground before passing to the concentrate CIL circuit via preaeration tanks designed to achieve 18-h contact with oxygen.

Gold recovery improved from 92% to 98% with two solution changes. The presence of carbon-in-leach process (CIL) was shown to achieve a similar gold recovery. Lead nitrate was shown to be beneficial in reducing residue grades in all cases. Fine grinding of the concentrate to 22 mm with CIL leaching improved recovery further to 98.6%.

The silver grade of the combined concentrate was about 63 percent with about 77 percent recovery. CIL testing of the cleaner tails from Master Composite Test extracted about 37 percent of the gold and 40 percent of the silver in the cleaner tails. Overall, this would increase gold and silver recovery by about 1.6 and 2.4 percent, respectively.

The CIL process The carbon-in-leach (CIL) process, illustrated in Figure 3 is a variation of the CIP process. In this process carbon is added directly to the leach circuit so that the leaching and adsorption processes proceed simultaneously. Capital cost is reduced, as …
