Frothers are usually added to the pulp just before its entrance into the flotation machine. The quantity of frother varies with the nature of the ore and the purity of the water. In general from .05 to .20 lbs. per ton of ore are required. Some frothers are more effective if added in small amounts at various points in the flotation machine circuit.

For example, the ore in the Nchanga processing plant in Zambia contains 4.7% copper. The copper content achieved to 50% ~ 55% through flotation by adding 500g/t of lime (pH 9 ~ 9.5), 10g/t of cresol (foaming agent), 60g/t of ethylxanthate, 35g/t of amyl xanthate, 1kg/t of sodium sulfide, 40g/t of palmitic acid and 75g/t of fuel oil.
Grinding balls for mining are made from various metals such as steel, hard metal and ceramic. However, they are commonly manufactured from steel and steel alloys which have superior resistance to abrasion and low wear rates. Hardness might be between 15 and 66 on the Rockwell Scale or between 85 to 105 on the Vickers hardness scale for certain steel alloy grinding balls. These hard-wearing balls are available in almost any size from 0.5 to 76.2 mm in diameter.
Industrial magnetic separator is applied to the broad scope of materials including metal and non-metallic minerals and iron-bearing materials like magnetite, ilmenite, pyrite.These days, industrial magnetic separator becomes more and more popular with increasing demand for magnetic separators in magnetic separation industry. Now, the machine is almost suitable for the separation of all kinds of metal and non-metallic minerals.
The flotation of copper oxide ore includes direct flotation and indirect flotation. Direct flotation is mainly used to treat copper oxide ores with simple mineral composition and uncomplicated properties; indirect flotation is to sulfide copper oxide ores by adding sulphide agent, and then flotation with common sulphide flotation agent. This method requires high sulphidation effect, and it willdirectly affects the flotationeffectof sulphide ores.

The Jet 350017 milling/drilling machine is a two-in-one lathe machine that gives you double the efficiency at a reasonable price of around 1700 $. It has a durable iron column, a knob that is easy to operate, a crystal clear depth gauge and variable motor speed which can reach a speed of 2500 rpm.
A mine that has improved in all four elements of productivity that underpin MPI—labor, capital expenditure, nonlabor operating costs, and production volumes—will move from its starting position (as shown by the dark-blue bubble) into the green quadrant, and the bubble size will be the same size or smaller than in 2008. Such a mine will have reduced unit costs and raised output per employee without increasing its capital expenditures. This has represented a difficult challenge for mines since 2008: none of the mines in the sample studied have succeeded in moving into this quadrant.
In comparison with the one-time separation, magnetic separation is more effective in improving the recovery rate from 72.01% to 89.24%. Based on the experiments, FTM engineers design the manganese ore extracting plant as below.
