However, from radiometric dating and modelling of diffusion and heat and flow rates, about 270 Myr ago apparently sphalerite in the Upper Mississippi Valley District was deposited for about Myr in layers up to 5 cm total thickness at a rate of about μm/a (Barnes, 2015); this conclusion is in agreement with an independent estimation of Myr in duration (Rowan and Goldhaber, 1996).

A few years ago operators in the Lake Superior ironore districts were replacing all their smaller scraper hoists with hoists of 15 or more horsepower. More recently some companies are replacing 15horsepower hoists with hoists rated at 25 horsepower. This is mentioned because scraping has been practiced to the virtual exclusion of hand shoveling and sublevel hand tramming in these districts

while iron ore production has increased by more than half. During this period, mining other than gold grew faster than the rest of the economy. These industries are larger than most manufacturing subsectors: South African coal sales in 1997 were R16 billion, PGM billion and chrome R4 billion. Some of the largest current investment projects in South Africa are in these industries. Platinum

Iron and sulfuroxidizing bacteria (, Acidithiobacillus ferrooxidans) can break down goldhosting sulfide minerals in zones of primary mineralization, releasing the associated gold as they act. This process corresponds to the geology found in Modlešovice around the Jilove gold deposit. The solubilized gold can then be reconcentrated via biogeochemical cycling

The Per Geijer iron oxide apatite deposits are important potential future resources for LuossavaaraKiirunavaara Aktiebolag (LKAB) which has been continuously mining magnetite/hematite ores in northern Sweden for over 125 years. Reliable and quantitative characterization of the mineralization is required as these ores inherit complex mineralogical and textural features.

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world''s iron and steel industries. It is therefore essential for

Natural Gold Ores and Minerals: Gold and silver are obtained from a variety of ores. Most people think of nuggets and such, but the truth is that very little comes from nuggets nearly all newly mined gold comes from ores mined from the natural hard rocks that contain gold in tiny, even microscopic particles. This webpage is created to show what some of those ores look like. Gold is found

All ore deposits are mineral deposits, but the reverse is not true. Ore deposit is an economic term, while mineral deposit is a geologic term. Whether a given mineral deposit is also an ore deposit depends on many factors other than the level of concentration and the size of the deposit; all factors that affect the mining, processing, and transporting of the ore must be considered as well.
