The fine ore mill feed process, the control of process conditions
First, strengthen the ratio of the coarse ore grade ore crushing granted before the ore must be specified each of the positions fall within the scope of ore grade storage, according to the inspection station produced ore grade commanding position in the case of mine down, usually more than two thousand high conventional water supply milling grade ore smelting, less than 2 per thousand percolation below the mine to use. Second, the ore machine selection process ore into the plant control taste different, and carries a low dry ten thousandths of waste rock, waste rock if these can not be broken out before the election, made after fines are not removed in the process, will increase the amount of added crushing milling working hours, on the hydrometallurgical process system to produce a great deal of time, equipment, chemical raw materials and other aspects of waste, in view of this, an increase in ore crushing preselection process measures: 1, ore warehouse deck grizzly square hole instead by a 250mm × 250mm 200mm × 200mm, sampling monitoring indicates that more than 200 √ 2mm chunk of rock is substantially, grade or so in parts per million, an existing process waste rock. While commanding pour mine excavator will need to format the screen surface waste rock to clear them. 2, the addition of the conveyor head v detector tied four eight, below the range automatic high pressure air blowing waste rock and low grade ore 'added at three in the belt hand-selected debris facilities, broken section crushing process Sec closed mine is broken, first with coarse jaw crusher broken into, over 15mm × 15mm mesh sieve, sieve the broken back with inertia cone, sieve qualified pulp mill fines goal. Selected low-grade ore belt in use when mine broke percolation.
