As ore is transported from stockpile along a conveyor belt, an overbelt magnet removes ferrous-based junk from the stream. Following screening, the stream can be sampled with Multotec's hammer sampler. A semi-autogenous or ball mill then grinds and crushes the ore to a finer particle size, which is then fed to a trommel screen.

Multotec specialises in zinc and lead beneficiation equipment with over 50 years of global experience and leading technology. Our team of metallurgists and engineers will partner with you to customise your equipment, helping your process run more efficiently while lowering your overall cost per ton.

The 2 major western phosphate rock ore deposits are located in southeastern Idaho and northeastern Utah, and the beneficiation processes used on materials from these deposits differ greatly. ... Dried or calcined rock is ground in roll or ball mills to a fine powder, typically specified as 60 percent by weight passing a 200-mesh sieve. Rock is ...

Indian blast furnaces are fed with lump iron ore (10 - 40 mm) and sinter as burden. Sinter is a prepared burden, where iron ore fines of size -10 + 0.15 mm are agglomerated using mainly flux and coke. Iron ore fines of less than 0.15 mm are not utilized in sintering technology and hence are mostly discarded at mines during processing as slime.

Pelletizing of iron ore was started in the 1950s to facilitate the utilization of finely ground iron ore concentrates in steel production. For the pelletizing of iron ore there are two main types of processes namely, the straight travelling grate (STG) process and the grate kiln (GK) process. In the STG process, a stationary bed of pellets is ...

Hard ore Work Index 16 = 100,000/65,000 = 1.54 kwh/t. For the purposes of this example, we will hypothesize that the the crushing index of the hard ore with the …

Many older operations have rod mills in combination with ball mills. Ball mills are a similar shape to that of the rod mills except that they are shorter with length to diameter ratios of 1 to 1.5. As the name implies, the grinding media in these mills are steel balls. The particles size of the feed usually does not exceed 2.5 cm.

The Mineral Processing Flowsheets shown on the following pages are based on actual data obtained from successful operating plants. Metallurgical data are shown in these flowsheets which incorporate Crushers, Grinding Mills, Flotation Machines, Unit Flotation Cells, and Selective Mineral Jigs as well as other standard milling equipment.
