Mineral processing
The hydrocarbon tail needs to be short to maximize the selectivity of the desired mineral and the headgroup dictates which minerals it attaches to The frothers are another important chemical addition to the pulp as it enables stable bubbles to be formed This is important as if the bubble coalesce, minerals fall off their surface...

Autogenous and Semi
intermediate size ready for final grinding in a ball mill, pebble mill, or VERTIMILLTM Wet grinding is accomplished in a slurry of 50 to 80 percent solids AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill...

Underground mining (hard rock)
A three-dimensional model of a modern underground mine with shaft access Underground hard rock mining refers to various underground mining techniques used to excavate hard minerals, usually those containing metals such as ore containing gold, silver, iron, copper, zinc, nickel, tin and lead, but also involves using the same techniques for excavating ores of gems such as diamonds or rubi...

Gold extraction
A 20Mt/a mill will have a capital cost within $10,000 /t/h and $20,000 /t/h (Lane, Fleay, Reynolds, & La Brooy, 2002) Typical operating costs for mills used in gold extraction are summarized in Table 3 The selection of a mill size is ultimately a function of the economics of the project and which mill size will maximize the project NPV...

Rod mills, how they function
But for comparison, rod mills would operate between 50% to 95% of the critical speed The faster the mill speed, the greater the wear on the rods and liners So, the general rule of thumb for rod mills is to operate no faster than the speed that will obtain the desired product size...

Geometallurgy
Geometallurgy relates to the practice of combining geology or geostatistics with metallurgy, or, more specifically, extractive metallurgy, to create a spatially or geologically based predictive model for mineral processing plants It is used in the hard rock mining industry for risk management and mitigation during mineral processing plant design...

Bond Work Index
Ball mill design requires a Bond work index, BWi, for ball mills at the correct passing size; SAG mill design requires an appropriate SAG test, for example, SPI (Chapter 5) Flotation design needs a valid measure of kinetics for each sample, including the maximum attainable recovery and rate constants for each mineral (Chapter 12) Take care to ....
