MINERAL ECONOMICS

•Limiting factors in mining•Minerals are immobile and they go on depleting unlike agriculture etc.•Companies should find new deposits•Production costs may increase(factors?) •Estimtes of ore supply may be incorrect.

•.

Mineral economics

Minerals from foreign and small producers result in over supply.

Reservoir of scraps depress market Prices of certain minerals are fixed by

government.(?). Mineral subsitutes.

Mineral economics

A country’s economic and social development is reflected by the discovery, exploration and exhaution of its mineral resources.

Mineral economics

Periods1. Period of mine development (many ldc’s)2. Period of smelter development(australia)3. Period of industrial development(soviet

union)4. Period of rapid depletion of cheap raw

materials.(usa)5. Period of decreasing internal and

external markets.(england)

So to control its mining destiny a country should have some economic policy.

Financing and marketing of mines In mining risk is higher but expected return

and pay back period is short, Minerals as well as mines can be sold. A mining engineer determines value of

mine. Mineral deposit worth may become more if

it is

Mineral deposit worth may become more if it is

1. Large2. Easily accessible3. In great demand4. Favorably located5. Cheaply mineable6. Military importance.

Potash is the common name for various mined and manufactured salts that contain potassium in water-soluble form. potassium chloride (KCl).

potassium carbonate (K2CO3) Fertilizer,fire extinguisher

phosphate, an inorganic chemical, is a salt of phosphoric acid.

. In mineralogy and geology, phosphate refers to a rock or ore containing phosphate ions

In agriculture Part of bone and teeth

Clay is a general term including many combinations of one or more clay minerals

In medicine, clay utensils,bricks etc

Gravels, roads, concrete Molybdenum(III) chloride MoCl3 (dark red solid) Molybdenum is also used in steel alloys for its

high corrosion resistance

The ability of molybdenum to withstand extreme temperatures without significantly expanding or softening makes it useful in applications that involve intense heat, including the manufacture of armour, aircraft parts, electrical contacts, industrial motors and filaments.[7][36]

Galvanization, which is the coating of iron or steel to protect the metals against corrosion,

zinc is used as an anode material for batteries

manganese Used in steel With aluminium as alloy for corrosion
