Photos of Natural Platinum Ore, Platinum and Palladium. Palladium occasionally occurs alloyed with gold. In Brazil, such palladium gold in a limestone close to the contact of an igneous rock. In Canada, platinum and palladium are obtained from the mattes obtained by smelting the nickel-copper ore of Sudbury, in Ontario.

Platinum-group minerals (PGM) and native gold are reported in association with gersdorffite nickeline from the Thompson mine, Thompson Nickel Belt, Manitoba, Canada. Four PGM-gold-bearing ore types are distinguished on the basis of mineral assemblages and host rocks: I. Irarsite in massive Ni sulphide ore hosted by metapelite; II. Gold, sudburyite, testibiopalladite-antimonian michenerite ...

Deposits in which the ore minerals have crystallized directly from a magma. Generally found in mafic or ultramafic igneous rocks, typically layered complexes. Three major deposit types: i) Nickel-Copper Deposits ii) Chromite Deposits iii) Platinum Group Elements Deposits Minor amounts of Cr and PGE are also recovered from eluvial or

The cobalt-arsenide ores of Bou Azzer are located along the borders of serpentinite massifs (Upper Proterozoic ophiolite complex) in carbonate-quartz lenses resulting from hydrothermal carbonate alteration of serpentinite. The cobalt ores contain an average gold content of 5–20 ppm; gold is mainly located in skutterudite (120 ppm av.), whereas the Fe-arsenide (loellingite) contains 1 ppm ...

In some deposits the Ni is associated with concentrations of platinum-group elements (PGEs) and copper, which increase the value of the nickel ore deposits. For example, the Noril’sk Ni-Cu-PGE deposit in Russia is estimated to have a value of approximately $1 trillion, representing one of the most valuable deposits in the world.

In other situations, platinum is obtained as a by-product when ores of other metals, such as copper and nickel, are refined. Modern Platinum Mining Techniques. Most of the mining for platinum ore occurs deep underground. To extract the mineral-rich materials, miners pack explosives into holes drilled in the rock and blast it into smaller pieces.

Gold: A test known as Darton's is believed to be a valuable means of detecting minute quantities of gold in rocks, ore tailings, etc. Small parts are chipped from all the sides of a mass of rock, amounting in all to about | ounce. This is powdered in a steel mortar and well mixed. About half is placed in a capacious test tube, and then the tube is partly filled with a solution made by ...

The Platinum Group of Elements (platinum, palladium, iridium, osmium, ruthenium, and rhodium) are rare, extremely scanty, noble, and precious transition metals that naturally coexist with nickel, chromium, copper, cobalt, gold, and silver. The metals occur by a unique mineralizing process, are spread closely in the Periodic Table, and are ...

rock formations that form large plateaus. Iron-ore in north Sweden, copper and nickel deposits in Ontario, Canada, iron, nickel, chromites and platinum in South Africa are examples of minerals found in igneous and metamorphic rocks. Sedimentary rock formations of plains and young fold mountains contain non-metallic minerals like limestone.

Gold and silver metals are obtained from a variety of different types of rock ores. Most people think of gold nuggets and such as the source of gold, but the truth is that very little of the new gold produced comes from nuggets - nearly all newly mined gold comes from ores mined from the natural hard rocks that contain gold in tiny, even ...
