It is measured by applying graduated pressure to a cube, 1 in ( cm) square, of the rock tested. A crushing strength of 4,000 lb means that a cubic inch of the rock withstands pressure to 4,000 lb (111 kg/cm 3) before crushing. The crushing strength is greater with shorter prisms and less with longer prisms. Ref: Fay ii.
Gneiss is a foliated metamorphic rock identified by its bands and lenses of varying mineral composition. Some of these bands (or lenses) contain granular minerals that are bound together in an interlocking texture. Other bands contain platy or elongated minerals that show a preferred orientation that parallels the overall banding in the rock.
Hardness is a mineral's resistance to scratching, and shows the strength of a mineral's atomic bonds. For example, take a human fingernail. It has a hardness of on the Mohs hardness scale, which is the standard for measuring a mineral's hardness; 1 is really soft and 10 is extremely hard.

Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.
MINERAL PROPERTIES: TENACITY. Tenacity describes the reaction of a mineral to stress such as crushing, bending, breaking, or tearing. Certain minerals react differently to each type of stress. Since tenacity is composed of several reactions to various stresses, it is possible for a mineral to have more than one type of tenacity.
Mar 10, 2014 · After extraction, many types of raw minerals are then subject to processes such as crushing, milling, washing and chemical treatments. Wastewater is generated during mineral processing (, stone cutting, wash water, scrubber water), from equipment cooling, from mine dewatering, and from stormwater runoff at mines and processing plants.
