The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.

The depletion allowance is one way to accomplish this. Since minerals are a finite source and will eventually play out, the IRS code generally allows royalty owners to deduct up to 15% of the income from their mineral interests.

Mineral sands are old beach, river or dune sands that contain concentrations of the important minerals, rutile, ilmenite, zircon and monazite. These 'heavy' minerals have a relative density of between 4 and g/cm 3 and are much heavier than common sand minerals such as quartz which has a density of around g/cm 3.

RADIOMETRIC TIME SCALE. The discovery of the natural radioactive decay of uranium in 1896 by Henry Becquerel, the French physicist, opened new vistas in science. In 1905, the British physicist Lord Rutherford--after defining the structure of the atom-- made the first clear suggestion for using radioactivity as a tool for measuring geologic time

There are different types of chemical weathering, the most important are: Solution - removal of rock in solution by acidic rainwater. In particular, limestone is weathered by rainwater containing dissolved CO2, (this process is sometimes called carbonation). Hydrolysis - the breakdown of rock by acidic water to produce clay and soluble salts.

Data on vitamin and mineral metabolism and requirements during pregnancy are scanty, and determining the consequences of apparently deficient or excessive intakes is not easy . In pregnancy, maternal metabolism is altered by hormones that mediate the redirecting of nutrients to the placenta and mammary gland as well as the transfer of nutrients to the developing infant.

used in mineral investigations to map low-velocity alluvial deposits such as those that may contain gold, tin, or sand and gravel. Applications in geoenvironmental work include studying the structure, thickness, and hydrology of tailings and extent of acid mine drainage around mineral deposits (Dave and others, 1986). THERMAL METHODS

Selecting the correct mineral supplement is important for efficient reproduction, high milk production and animal health of both the cow herd and calves.
