Mining

Platinum, like gold, can be alluvially transported from a lode and found in ore-grade sand deposits, so yes, conceivable, platinum ores can be found on the beach. Platinum nuggets from placer deposits are far rarer than gold nuggets and are highly valued by collectors.

0%, it just looks like gold.

After information had confirmed that James Marshall had struck gold in 1848, residents who lived in in Oregon, Hawaii, Meico and Central America, got the news first and moved there, becoming the first of the miners. The Gold Rush was the largest mass migration in US history.

Yes. Pyrite is inorganic. It is not produced from any processes that involve organisms.

Both of them utilize expectation-maximization strategy to converge to a minimum error condition. While K-Medoids require the cluster centters to be centroids, in k-Means the centers could be anywhere in the sample space. k-Medoids is more robust to outliners than k-Means therefore results in more quality clustering. It is also computationally more complex.

Mining prior to the arrival of the Europeans cannot be defined by a date. For thousands of years, the Aborigines had already been mining ochre (used in art and for ceremonial purposes) and stone. They established quarries and transportation routes for trading between tribes. In regards to European settlement, mining started following the discovery of coal in the Newcastle area. Originally discovered by excaped convict William Bryant in 1791, it was not reported until an English officer found a coal seam, in 1797, whilst searching for escaped convicts. Coal was mined and exported, beginning in 1799. The first coal mining settlement was established at Newcastle in 1801.

An emeralds streak is believed to be white, green, and/or yellow.

Nothing , they think that pockets of public are gold mines

The main ore of sodium is salt. Sodium can be extracted in various ways from salt and electrolysis is one of the most effective methods.

Minerals have a definite chemical composition, are solid, are inorganic, are naturally occurring, and have a crystalline structure.

Culprit and Chalococite. (Copper is found combined with oxygen to form culprit, or with sulfur to form chalcocite.

The International Seabed Authority (ISA) is an intergovernmental body based in Kingston, Jamaica, that was established to organize and control all mineral-related activities in the international seabed area beyond the limits of national jurisdiction, an area underlying most of the world's oceans. It is an autonomous organization having a relationship agreement with the United Nations.

Because it depends on what type of ore it is. If it is a certain type of ore, then there is a certain amount of value in money for it. That's Why.

Galena is a mineral composed of lead and sulfur, and this mineral, PbS, is the primary ore of lead. There is also a good bit of silver associated with galena, and silver is often recovered as a byproduct of lead processing. A link can be found below to check facts and gather more information.

There are Physical Properties: Color, Density, Viscosity, Hardness, Lustre, Crystal Shape, Ductility, Cleavage, Solubility, Maleability, Boiling Point, Melting Point, and Conductivity!

An open question exists as to why an individual would want to prevent uranium mining. Until a better, cleaner way to generate electric power comes along, we are stuck running what we have (including nuclear power plants). Our focus needs to be developing and moving to those cleaner power generation technologies. Uranium is a necessary nuclear fuel, and our efforts should be aimed at safety of nuclear facilities and at environmental issues surrounding uranium mining (and all mining, for that matter).

This is called removing overburden, and usually requires heavy machinery; eg: to access coal seams, sometimes entire mountain tops are removed.

galena, pyrite, and hematite all happen to be distinct in their metallic luster.
