J. Miner. Process., 12: 285--304. An efficient and automated ore-dressing plant simulator has been developed. In this simulator, stream variables can be used to describe a large number of unique solid particles that have a wide range of properties. Consequently, a large number of simultaneous equations need to be solved.

Ore-dressing methods fall naturally into two general subdivisions— (1) concentration methods and (2) direct-recovery methods (amalgamation and leaching or wet methods). Concentration methods are employed to remove worthless gangue material and concentrate the valuable minerals of the crude ore in a smaller bulk.

3. Flotation equipment. At present, the lead-zinc dressing plant uses 5A and 1A flotation machines. Due to the flotation machines' long history, equipment operation's high failure rate, and the poor separation index, we replace all the flotation machines with BF flotation machines. BF-2.8 flotation machines are used for priority …

The particle size is of particular importance in this process. If the particles are too large, unwanted accessory minerals cannot be separated from the ore. The ore concentrate obtained only has a low purity. Overgrinding, on the other hand, results in high milling costs and low throughput as well as an increased need for chemicals in flotation.

The finely crushed ore is trans-ferred on a belt conveyor to an ore bin adjacent to the mine hoist. Via a 58.6-m-long conveyor resting on six load cells the exact quantity of ore is dumped into the skip and hoisted to the ground level. From here the ore is transported on a belt conveyor to the adjacent ore dressing plant. Finally, the ore con-

The roasting cost works out at approximately $1.22 per ton of concentrate, distributed as shown in Table 99. At MacLeod Cockshutt Gold Mines, Ltd., the cost of roasting in 1941- 1942 was 32 cents per ton milled or $1.25 per ton of ore roasted, while at Lake Shore mines for the same year the cost was about 80 cents per ton roasted.

The ore lumps from the mines have the lump size of 10 - 100 cm while the individual minerals have grain sizes below 0.1 mm. Hence, the first step in any ore dressing plant is to aim at liberation by size reduction or comminution. Comminution of any ore is carried out in several stages using different crushing equipments.
