Pyrite Mining | Processing Equipment | Flow Chart | Cases
What is Pyrite. Commonly called fool's gold, pyrite is the Earth's most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.

Impact Crusher
The three types of crushers most commonly used for crushing CDW materials are the jaw crusher, the impact crusher and the gyratory crusher (Figure 4.4).A jaw crusher consists of two plates, with one oscillating back and forth against the other at a fixed angle (Figure 4.4(a)) and it is the most widely used in primary crushing stages (Behera et al., 2014).

Diamond Processing Plant & Equipment
Capacity of diamond pans is normally 5 to 6 tons per square foot of effective area per 24 hours and require 1 to 1½ horsepower per ton of feed. Ratios of concentration vary, usually from 10:1 to 50:1 depending on the amounts of heavy minerals associated with the diamonds. Recoveries up to 97% are sometimes possible.

4. SIZE REDUCTION
Size reduction equipment is divided into Crushers, Grinders, Ultrafine grinders and Cutting machines. Crushers do the heavy work of breaking large pieces of solids into smaller lumps. Primary crushers are run on materials out of mine the size of which may reach more than one meter and breaking it into 150 – 300 mm lumps. A secondary

Using Rock Geomechanical Characteristics to Estimate Bond
The BRMWI is a measure of the resistance of the material to crushing and grinding in a rod mill and is used to calculate the grinding power needed for a given material parcel regarding rod mill grinding conditions. Along with other Bond tests, BRMWI is used to design semi-autogenous mills using semi-experimental relationships [24].

Magnetic Separation of Pyrite
It was thought that crushing of pyrite in coal may not produce enough friction heat to cause surface reactions to an extent comparable to that caused by crushing pure pyrite. Therefore, a sample of hydrothermal Rico pyrite (0.3 x 10 -6 for 1/8-inch lumps) was crushed to less than 150 µ in an agate mortar.
