From the perspective of metallurgical processing, gold ores can be classified into free-milling and refractory ores. Their extractive metallurgy are largely driven by mineralogical factors such as: gold particle size, association with other minerals, coatings and rimmings, presence of cyanicides, oxygen consumers and preg-robbers, presence of refractory …

The local similarity of the attribute Gold ore grade was modelled by a symmetric distance function illustrated in Fig. 1 and defined by Eq. (2). (2) y =-1 71 x + 1 Here y expresses the local similarity value and x indicates the remainder of the two Gold ore grade values in the queried ore and the case. The denominator in Eq.
Refractory gold ore pretreatment Treatment of refractory gold ore (whole ore and flotation concentrates) has become more prominent since the 1980s, with many gold discoveries often including ores that are wholly or partially refractory. Refractory pre-treatment processes include pressure oxidation, biological oxidation and various forms of ...
As deposits with free, coarse gold were depleted and the volume of mining increased, process flowsheet design became more and more complicated. Gravity was the first method developed to recover gold from ore. But, currently there are very few deposits left that contain ores suitable for gold recovery strictly by this method.
The gold contained in the ore occurs at an average of. 17 opt (ounces per ton of ore). The gold is within the sulfide mineral matrix, which is not exposed (and therefore can not be dissolved by) a cyanide leach solution. Also the ore contains carbonaceous matter which absorbs gold in the conventional leaching process.

The manual is all about VAT Leaching Technology which is a low cost technology for recovery of gold from fresh ore or from tails left from previous CIL process and from Small Scale Miners.
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 …
Testwork was undertaken to develop a flowsheet that would maximise gold recovery from an ore containing 3 g/t Au and high levels of arsenic. Treatment of the sulphide ore …
The extent to which fine crushing can be carried out will vary and depends on the ore characteristics, plant and crusher design. Unfortunately, the ore characteristics are generally beyond our control, so the concentration of effort lies primarily on the plant arrangement, equipment design and operation.

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.
A block-flow diagram of a typical CIP plant for a non-refractory gold ore is shown in Figure 2. Table I and Table II illustrate the capital and operating cost breakdowns for a typical South African gold plant. These figures are not a standard but reflect the nature of the ore and the design basis for a particular situation.
