Thus, a reasonable cost figure for processing a ton of loaded carbon by the smelting technique is 5,500 to 7,000. In the preferred method, gold recovery from activated carbon is accomplished by desorbing the gold and silver values from the carbon and electrowinning the values from the resultant strip solutions.
Lock up of gold on mill liners, sumps, gold traps etc. This is common. Mill upsets and coarse grinds floods and plant disruptions can occur, which may not be picked up with infrequent sampling.

can be recovered by thickening the mill slurry prior to leaching, and again . thickening the leach plant tailings prior to discharge. For example, if the feed and discharge from cyanidation/gold recovery can be thickened to 60% solids, and the leach/gold recovery operation is conducted at 40% solids, the net result

geothermal power plant Haselrain. is extracted from a depth of 1 547 m at a rate of 25 l/second and returned at approx. 25 °C. In the heat recovery system, the return water from the distribution network is first preheated with the geothermal water by means of a heat exchanger from approx. 53 °C to 57 °C
At current gold prices this is worth about US600. Both smelter treatment charges and oxidation or bioleach costs are at least 200/t of concentrate and payables/recovery in the 90% range, so a minimum GSR for effective downstream processing is around Clearly this is a function of gold price, but in the current gold price and cost ...

The Cyanidation Process or CYANIDE LEACHING is 'most notably used in the recovery of gold. Safety and environmental concerns are of prime importance in the operation of a cyanidation plant. As we get farther into this type of recovery you will see why. The preparation of the ore for processing is similar to flotation.
types, might be suitable for evaluation of plant design and metallurgical recovery and grade. Unfortunately, ore is seldom presented to the processing plant in such a manner. Unless a significant blending process is allowed for prior to processing, varying ore types can be mined and processed with little or no blending.
Concentration and Recovery Formulas. These are used to compute the production of concentrate in a mill or in a particular circuit. The formulas are based on assays of samples, and the results of the calculations are generally accurate— as accurate as the sampling, assaying, and crude ore (or other) tonnage on which they depend.
Concentrator Operations. The ores received into the plant, after conventional washing, crushing and grinding, are subjected to differential flotation for the recovery of sulphide copper mineral for smelting and oxide (or nonsulphide) copper minerals for leaching. Sources of feed materials to the concentrator are: (a) Nchanga West orebody.
