Leaching gold in Calcine. The principal cyanides in the calcine are copper, ferrous iron, and smaller amounts of Mo, Co, Ni, Mn, etc. Most of the cyanicides can be removed by water washing, but this step cannot be used owing to the loss of about in gold resulting from the use of salt in the roast.

The thiourea (TU) leaching of gold from refractory ores can be considered an alternative to cyanidation. However, the high reagent consumption causes an increase in cost, which seriously limits its use. In order to effectively reduce the TU consumption, it is necessary to analyze the influencing parameters of gold recovery and TU consumption and apply them to the prediction of the TU leaching ...

PROCESS FLOWSHEET DESCRIPTION: Continuous countercurrent decantation cyanidation flowsheet. ORE TREATED: Gold and silver ores amenable to the cyanidation process and where economics justify plant outlay. ADVANTAGES: By producing the precious metals in bullion form, the highest net return is realized on many gold and silver ores. Where the tonnage available for treatment justifies the capital ...

Abstract Electronic waste is a dominant global issue with over 50 million tons generated annually. Still, as an amalgamation of precious and rare raw materials, electronic waste is a considerable economic resource with the most valuable components located on the printed circuit boards. Gold is widely used in electronics in numerous applications, although principally for contact points and ...

Beneficiation. Mineral beneficiation begins with crushing and grinding of mined ore for nearcomplete separation of ore and gangue minerals as well as between ore minerals. Each processing step is designed to increase the grade (concentration) of the valuable components of the original ore.

The roasting cost works out at approximately per ton of concentrate, distributed as shown in Table 99. At MacLeod Cockshutt Gold Mines, Ltd., the cost of roasting in 1941 1942 was 32 cents per ton milled or per ton of ore roasted, while at Lake Shore mines for the same year the cost was about 80 cents per ton roasted.

The introduction of synthetic, high molecular weight, watersoluble polymer flocculants was a turning point in tailings dewatering within the minerals industry. Gravity thickening had previously relied on coagulants and natural products ( starch) to aggregate particles and accelerate settling. Synthetic flocculants enable much larger ...

The core of thickening process control is to adjust the underflow ore drawing speed in time according to different working conditions. When flocculant is added, it is necessary to adjust the amount of flocculant in time to obtain the best sedimentation velocity, so that the underflow ore discharging speed and ore discharging concentration are in the best matching interval.

A gold mine was experiencing ongoing problems with froth formation on its preleach thickener. Feeds with entrained air are a challenge to the thickener flocculation process. Aerated thickener feed that makes its way into the body of the thickener tends to carry fine particles to the thickener surface to form froth.
