In the process of discovering the nature of a rock and Identifying Minerals, the mineralogist may derive the necessary information by a careful study of its external appearance and characteristics; the form of crystallization, hardness, specific gravity, colour, streak (the colour when scratched, or when rubbed on a piece of porcelain), and also from its behaviour when exposed to the action of Chemicals or heat.
A method of treating mineral slurries to inhibit bacterial growth includes adding an effective amount of one or more of sodium N-methyldithiocarbamate or methylammonium monomethyIdithiocarbamate to the mineral slurry to inhibit bacterial growth.
While most mineral deposits can be mined by either surface or underground methods, some minerals can only be recovered in a hybrid manner, usually by initial extracted by open pit mining, followed by underground methods.
HARDNESS The hardness of a mineral can be measured by its resistance to scratching or abrasion. The Mohs scale is a set of 10 common minerals chosen for comparative hardness.
In the terrace-mining method, though, steps or "benches" are created parallel to the pit on the way to the bottom. The benches can be used as exploration spots, where miners search for emerald-rich rock, or they can be used to haul away waste rock.

The most important method used to extract the minerals from the earth is surface mining. It is surprising to notice that 70 percent of the minerals extracted from the earth are through this process. The basic material used for construction purposes like crushed rocks, sand and gravel is obtained through this method.
Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic conditionthat is, the surfaces are either repelled or attracted by water.
This method is used frequently in the analysis of vanadium, where ammonia gas is used in the reaction cell. The analysis of selenium by this method is worth noting.
Universal separation method, because by using flotation can be separated almost all minerals. It is used for all types of ores and minerals (chalcopyrite, molybdenite, galena, sphalerite, gold , talc, mica, carbon, rare earth mineral , uranium minerals , and others ).
During the exploration process, a mining company seeks an area where the desired mineral resource is concentrated and attempts to determine the size of the ore body and the mineral resources ore grade. Higher ore grades (higher concentrations) make the mining project more viable (see Table 1).
Heap leaching (HL) is a flexible and economic mineral processing method, commonly used to extract gold from low-grade gold ores. In this process, ore is firstly crushed to fine particles. By spraying leaching solution to the large piles, the gold-containing solution is leached.
Cost Approach Historical Context in Minerals Appraisal Cost Approach Methods used extensively by Canadian and Australian practitioners For raw exploration land through early
Minerals in the terrestrial environment may be mined using underground or open cast methods. Open cast mining is used in situation where the minerals are relatively shallow or less concentrated. Underground mining is used for deposits at greater depth, higher grade deposits, or vein ores.
The method used depends on the type of mineral resource that is mined, its location at or beneath the surface, and whether the resource is worth enough money to justify extracting it. Each mining method also has varying degrees of impact on the surrounding landscape and environment.
