Bottle Roll Test, a simple simulation of CIL Process in Gold Mining - Free download as PDF File (.pdf), Text File (.txt) or read online for free. Gold mining usually use CIL (Carbon in Leach) process in their plant system to get gold from its ore. To well known how to design CIL plant, we simulate the plants using bottle roll with the same amount of situation so we may get the best .Next, the ore samples were put into a bottle containing 6 kg of water so that the percentage of solids in the intermittent bottle roll test was 33%. Cement, Portland-PCC(Figure 5 (a)), as a pH modifier are added to the bottle to obtain a pH of around 10.5. The presentation will describe the procedure for field-test data analysis and discuss how the laboratory bottle-test data correlate with field tests data, thus validating the new bottle-testing .
