Most rock deposits contain metals or minerals, but when the concentration of valuable minerals or metals is too low to justify mining, it is considered a waste or gangue material. Within an ore body, valuable minerals are surrounded by gangue and it is the primary function of mineral processing , to liberate and concentrate those valuable minerals.

METAMORPHIC ROCKS (6) The minerals occurring in metamorphic rocks depend on the minerals present in the original rock and the nature of the metamorphic processes that occur. Metamorphic rocks commonly contain abundant silicate minerals; many of these silicate minerals are minor or nonexistent in rocks crystallizing from magma. This fact is

Mineral processing operations present many challenges to process control due to variations in unmeasured ore properties, material transport delays, and nonlinear response characteristics. The conventional control approach relies mainly on the proportional-integral-derivative controllers or rule-based strategy for process control, which inherently does not have the capability to efficiently

Weathering: A process of disintegration and decomposition of rocks and minerals which are brought about by physical agents and chemical processes, leading to the formation of Regolith (unconsolidated residues of the weathering rock on the earth’s surface or above the solid rocks).

Chemical Weathering: Processes that break a rock apart by changing the chemical composition of minerals or dissolving minerals entirely. For example, salt dropped into a glass of water will dissolve, in which case it will change from the mineral (NaCl) to ions (Na + and Cl
To obtain minerals suitable for age-dating and other analyses, it is necessary to first reduce the mineral-bearing rock to a fine, sand-like consistency. Reducing whole rock requires crushing, grinding, and sieving. Ideally, the reduced material should range in size from 80- to 270-mesh (an opening between wires in a sieve). The openings in an 80-mesh sieve are equal to 0.007 inches, 0.177

Mineral processing Wikipedia. Dewatering is an important process in mineral processing the purpose of dewatering is to remove water absorbed by the particles which increases the pulp density this is done for a number of reasons, specifically, to enable ore handling and concentrates to be transported easily, allow further processing to occur and to dispose of the gangue

Weathering processes break rocks into smaller pieces. There are two types of weathering: chemical and mechanical. Chemical weathering changes the chemical makeup of minerals and hence breaks them apart. For example, when sugar is stirred into water, the
