Complex ore - An ore containing a number of minerals of economic value. The term often implies that there are metallurgical difficulties in liberating and separating the valuable metals. Cone crusher - A machine which crushes ore between a gyrating cone or crushing head and an inverted, truncated cone known as a bowl.
ROCKY DEM is helping us to improve various processes. The use of simulation tools can quantify the design improvements and gains; this is advantageous because mining uses large equipment that without computer simulation can cost millions for prototype development and testing.
Minerals processing is about extracting the valuable minerals contained in the mined ore and producing a saleable product or an enriched concentrate for further processing. It is important to maximise production rate and recovery of the valuable minerals and to minimise the cost of extraction.
Waste Initiatives Drum Crushers are robustly built units with great functionality – ensuring fast & easy crushing of your steel drums. Drum Crushers are suitable for sizes up to 205L, and are equipped with drum piercing spikes and a 30L oil retention tank to capture any residue.
It is recommended to use sieves with hole diameters of 3.15, 16, 31.5, 45, 63 and 100 mm, if the measurement aims at the determination of conformity with ISO 17225 series. Table 3.5 shows an example of particle size of measured forest residue chips. In this example most of requirements of P16 can be fulfilled, only the amount of the coarse fraction (over-sized particle) is higher than ...
A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.. The unqualified term "coke" usually refers to the product derived from low ...
