The liberation degree of silver minerals in the grinding products was as high as 77.33% after using SCSM to grind the ore to 85% passing 74 μm, suggesting that most silver minerals in the ore have been liberated. The Ag content and Ag recovery of the silver concentrates were basically the same in the cases of grinding with SBSM and BM.
PFS HIGHLIGHTS: Probable Mineral Reserves totalling 102.1 Mt grading 0.41% copper, 0.26 g/t gold, and 2.30 g/t silver diluted. 22,000 tonnes per day ("tpd") open pit mining operation, with average annual production of 68.8 Mlbs copper, 55 koz gold, and 386 koz silver, over a 13-year Life of Mine ("LOM"). Low overall strip ratio of 1.1.
Of these three minerals, quartz was the hardest and kaolin the softest. The starting feed charge consisted of 3350/2360 μm size fractions of these minerals. The minerals were batch ground separately, and also as ternary mixtures mixed in the ratios of 1:1:1 and 1:1:2, by weight, for the same periods and under the same operating conditions.
The latest and most successful new comminution technology has been the high-pressure grinding rolls (HPGR), which have proved to be highly efficient in energy consumption and to have a relatively high throughput rate at low steel consumption. Already used extensively in cement plants worldwide, the first HPGRs in the mineral industry …

Limestone/quartz (Ls/Qz) feed mixtures were prepared in the proportions 10, 25, 50, 75, and 90%, as well as grinding each material alone (), and ground dry. These two materials were chosen not only because of their differences in grindabilities and their similar densities but also to simplify size analysis.

Abstract. Under an invariant and self-similar mill environment, batch wet grinding studies were carried out by grinding mono-sized fractions of quartz, chlorite and their binary mixture at different blending ratios. The results obtained indicate that the breakage behavior of both minerals as well as their mixture followed a first-order model.
