The design practice of the mining and metallurgical industry is typically separated between the technical and economic analysis, i.e. the technical flowsheet development and feasibility study are done separately (Khalesi et al., 2015). ... This chapter provides an overview of some of the key drivers for gold process plant design on an …

FIGURE 3-18 Cyanide leaching in tank at gold processing plant. Tank Leaching. As shown in Figure 3-10, tank or vat leaching would follow crushing, grinding, and flotation of ore, possibly with oxidation of the resulting concentrate to expose gold grains. Leaching is usually done at ambient temperature, and requires aeration to oxidize the gold ...

Exploring the Cyanide Leaching Process. Cyanide leaching is a method that has transformed the gold mining industry with its effectiveness and efficiency. The process involves a chemical reaction between cyanide and the minute particles of gold found within ore, forming a solubilized gold-cyanide solution.

The assumption is that ore has 2.5 ppm of gold and feed flow rate to the plant is 100 tons per hour. The cost of reagents per ton of ore and the gold price per gram is assumed to be $30 and $40 respectively. Tax and discount rates are assumed to be 10% and 15%, respectively. The tanks are also assumed to be perfect mixers.

The process is further complicated as the designer does not only need to find a set of design variables which results in a suitable metallurgical efficiency, but the plant design must also result in a near optimum return on investment. It is thus highly desirable to combine a costing and economic analysis model with the technical model for CIP.
