Orebody types Mineral Exploration, Evaluation

They are often referred to as “seams,” “reefs” or “lodes.” The orebody has a narrow width which may be anything from a few millimetres to many metres. Chromite seams are exploited in Zimbabwe at a width of 100mm whilst coal seams with a width of 100m, found in South Africa and other countries, are also regarded as “tabular.”

Jump to: navigation, search. A gold reef is where the gold is found still deposited in its original rock host. In Ballarat this rock was usually quartz, in what is described as a reef. Alluvial gold was gold that had come loose from its original host, and had been deposited by water action into creeks and rivers.

Unusually large deposits (>200Mt as suggested mining rate would be unobtainable) Very deep, flat ore bodies (production limited by hoisting limits of shaft) Steeply dipping tabular or massive deposits that are worked in steps towards great depths (limited to rate of deepening of the working, use #Tatman (2001))

Seismicity associated with mining - ScienceDirect

The gold-bearing reefs are mined at depths of down to more than 3 km below surface by stoping. This creates flat voids in the quartzitic strata extending laterally for distances of up to several kilometres with an initial excavated thickness of a metre.

Ore Body - an overview ScienceDirect Topics

The sheet, the most common shape in which sedimentary deposits occur, is a tabular body separated from other rocks by bedding planes. Veins are ore bodies formed when a mineral substance fills fracture cavities or when there is metasomatic substitution of mineral substances for rocks along cracks.

17-04-2021  Typically, gold is found in large veins, the result of cooled, cemented lava activity that was further abraded by the force of rivers and streams. Another clue to a true gold find is an absence of “cleavage,” a characteristic sought by geologists when they differentiate gold deposits from other minerals. Where to Find Gold in the US

Gold Milling Process -Primitive and Basic

Tiny, conical crucibles, capable of holding about a couple of ounces of gold are used; the gold-dust is melted in these with borax and niter as fluxes; the slag is lifted off the surface of the gold when the latter is supposed to be clean, by means of an iron rod, and the gold is then granulated by pouring into water.
