Factors influencing the rate of gold cyanide leaching

2011-5-1  Gold extraction per stage was ∼70% for Tests 1 and 2, but dropped to ∼60% in Test 3, which resulted in an increase in the predicted soluble losses from the last stage, from 0.003 mg/L to 0.019 mg/L. Intuitively, one might predict that the optimum pulp density is 50%, based on these results, but as shown in the next section, a more detailed cost/benefit analysis is needed to arrive at the true optimum.

Factors influencing the rate of gold cyanide leaching

2011-5-1  Highlights Worldwide gold recovery on activated carbon grew from zero to almost 70% in twenty years from 1980. The stellar attributes of carbon gold plants led to complacency in the industry in designing and operating these plants. Most CIP and CIL plants are overdesigned and operated sub-optimally. Optimum design criteria and operating conditions are easily determined with simple test

Optimization of some parameters of stirred mill for

2011-3-10  The optimum levels of variables were found to be 1.61 mm ball diameter, 10.56 min grinding time, 80% for ball charge ratio and 750 rpm stirrer revolution with a prediction of 3.28 μm for d 80. Once the optimal levels of the control factors were selected, the final step was to verify the improvement of grinding performance using these optimal ...

Comminution circuits for gold ore processing -

2005-1-1  For the vast majority of ounces of gold produced, comminution costs in the form of power, grinding media, and liners represent the single largest cost category of milling. Since, semi-autogenous grinding (SAG) ball-mill circuits represent the single largest type of gold milling comminution circuits, the chapter focuses on SAG.
