Mineral - Classification of minerals: Since the middle of the 19th century, minerals have been classified on the basis of their chemical composition. Under this scheme, they are divided into classes according to their dominant anion or anionic group (e.g., halides, oxides, and sulfides). Several reasons justify use of this criterion as the distinguishing factor at the highest level of mineral ...
The basic extraction of ore deposits follows these steps: Prospecting or exploration to find and then define the extent and value of ore where it is located ("ore body") Conduct resource estimation to mathematically estimate the size and grade of the deposit; Conduct a pre-feasibility study to determine the theoretical economics of the ore deposit.
Drill Hole #1 encountered silver ore at 80 feet below surface. Ore graded from 9.8 opt to 57 opt. Lost drill hole at 100 ft. Drill Hole #2 encountered silver ore at 90 ft. and continued to 310 ft. Ore grades ran from 2 opt to 74.3 opt. Need further funding or junior operators to continue development.
Platinum jewelry is rare, beautiful, and durable, and is therefore highly regarded. Native Platinum is the most significant source of the element platinum, although considerable quantities are also mined from the rare platinum arsenide mineral Sperrylite. The rare metals iridium, osmium, rhodium, and palladium are almost exclusively mined ...
South Africa is the world's largest producer of platinum, which is mined in an area called the Bushveld Igneous Complex. The PGM concentration is low, in the range of 2–10 ppm (g/t), and generally associated with base metal sulfide minerals. PGMs are recovered as a byproduct or co-product depending on their concentration in the ore.
May 10, 2018· The J-M Reef ore body in Montana contains mostly copper and nickel, with low platinum content as a byproduct. Gravel deposits in Alberta, Canada, provide a placer source for platinum in certain rivers, where it coincides with gold and other minerals. Platinum flakes can be recovered through gravel washings, shaking tables and other methods.
yield its valuable mineral at a profit. To be classified as platinum ore, the platinum content would have to make up a significant portion of the value of the ore. The recovery of trace amounts of platinum group metals from other ores in the final stages of refining does not make the rock platinum ore.
Platinum group metals are some of the rarest minerals on earth. When most people think of platinum group metals, they only focus on platinum and palladium.With a high resistance to heat and properties of incredible strength platinum and palladium are vital components of catalytic converters that clear poison emissions before they pollute the environment.
Dec 25, 2013· To get chance for shiny ingots (platinum) from ferrous ore, you'll want to pulverize redstone ore for the cinnabar, then use it in the induction furnace (or was it smelter? whichever one is in TE3, I get names mixed up all the time) with the ferrous ore and cinnabar for …
It is probable that all of the platinum in the world would fit into a square of less than 25 feet on each side or in an average American living room. Platinum is also more difficult to mine than is gold. Typically, the platinum mining process takes five to seven months and may require as much as 10 tons of ore to yield one ounce of platinum.

For the present study, every effort was made to enter ... in the conterminous United States have all been classified as placer gold-PGE deposits (Yeend, 1986), even where ...

The ore-forming minerals include sperrylite, cobaltite, pentlandite, niccolite, skutterudite, pyrrhotite, and chromite. The highest global share of chromium and platinum production originated from the Bushveld Complex alone during the last century which has enough reserve base to …
A major source of platinum is the ore sperrylite (PtAs 2). It is also found in the mineral cooperite (PtS). Platinum is also produced commercially as a by-product of nickel refining from copper-nickel ores. Isotopes: Platinum has 35 isotopes whose half-lives are known, with mass numbers 202 to 168.
An overview of Southern African PGM smelting R.T. Jones Mintek Private Bag X3015, Randburg, 2125, South Africa ABSTRACT The largest known platinum group metal (PGM) deposit in the world is the Bushveld Complex in South Africa, with the Great Dyke in Zimbabwe also being one of the biggest.
Olivine has several industrial uses. It is used as a flux for steel production, and is also an important ore of the metal magnesium. Peridot, the transparent olive-green to yellow-green variety, is a well-known gemstone. It is very popular in jewelry, and is used in many jewelry items including rings, bracelets, necklaces, and earrings.
