Leach Circuit Design Principles SRK Consulting

Designing a leach circuit should consider both ore-specific factors as well as factors involving the interaction between the ore and process equipment. Achieving the optimum leach performance involves combining operating parameters, such as grind size, residence time, chemical conditions (reagent addition levels, temperature, etc.), most of which interact with each other. Determining the

Leaching Plant Design Mineral Processing & Metallurgy

Leaching plants, faced with increased tonnage, coarse (up to —3/16″ solids) feed, longer retention time, erosion, corrosion and the high cost of space, must be compact, simple and highly efficient. The engineer faced with the obvious economy of using a few large agitators compared to many smaller units must also evaluate the design factors which will prevent the settling-out of solids

plant. The leach circuit comprises 22 tanks with a total volume of 44 000 m3 in two parallel streams that allows for a total retention time of 7 hours. Calcium cyanide is added at an addition rate of approximately 350 g/t. Due to the large tonnage multiplier, this equates to approxi-mately 1 000 (as 100% NaCN) tons of cyanide per month representing approximately 25% of the total operating cost

CIP/CIL Modelling AusIMM

The processes in which gold cyanide is adsorbed on activated carbon are very robust mechanically and very efficient metallurgically. Tolerant of plant upsets, changes in feed composition and “less-than-optimum” plant designs. Owners and operators often aren’t even aware that their plant design may be “less-than-optimum” because: Gold extraction efficiency is usually good enough even

sufficient free cyanide ions in solution to dissolve all the gold, otherwise it will be lost to tailings. The more gold which has to be leached, the more cyanide required. In practice, a balance is sought so that there is sufficient cyanide to leach the gold, but not so much that

The process design of gold leaching and carbon-in-pulp

Leaching reagents in the form of cyanide and an oxidant such as air or oxygen are added after thickening. Leaching takes place in a series of agitated leach reactors or pachucas. Before leaching the pH of the pulp is normally adjusted to a value of around 9.5–11 to ensure minimum loss of cyanide as hydrogen cyanide.

Cyanide Leaching Mining SGS Indonesia

Cyanide leaching has been the industry standard for gold processing for more than 100 years. During the cyanide leach process, a cyanide solution, or lixiviant, is percolated through ore contained in vats, columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns. It is then extracted from the pregnant leach
