Liquid immiscibility: sulfide ores containing copper, nickel, or platinum may form from this process. As a magma changes, parts of it may separate from the main body of magma. ... Native gold (Au) occurs in this rock as colloform bands, ... Ore genesis theories for these ores are wide and varied, ...
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) NickelCopper Deposits ii) Chromite Deposits iii) Platinum Group Elements Deposits Minor amounts of Cr and PGE are also recovered from eluvial or
metal ores (<1% copper, <1g/ton gold, < % nickel) previously considered uneconomical, became feasible with introduction of heap leaching technologies (Marsden, 2009). In consideration of ore types, a generalized diagram showing the applicable ore beneficiation technologies for oxide and sulphide ores versus ore grade is given in Figure 2.
Precious metals can be found in ore deposits along with sulfur, and are known as sulfides. Cadmium, cobalt, copper, lead, molybdenum, nickel, silver, zinc, and gold and platinum group metals can be found in sulfide forms. These concentrated ore deposits are considered low grade because of the economic costs associated ...
basic process for extraction of the platinum metals has remained essentially the same. Rustenburg converter matte contains about 46 per cent of nickel and 28 per cent copper, together with some other base metals and sulphur. The platinum group metals, together with some gold, total about fifty ounces to the ton.
Metal ores are generally oxides, sulfides, silicates, native metals such as copper, or noble metals such as gold. Ores must be processed to extract the elements of interest from the waste rock. Ore bodies are formed by a variety of geological processes generally referred to as ore genesis

GOLD IN MINERALS AND THE COMPOSITION OF NATIVE GOLD By ROBERT S. JONES and MICHAEL FLEISCHER ABSTRACT Gold occurs in nature mainly as the metal and as various alloys. It forms complete series of solid solu tions with silver, copper, nickel, palladium, and platinum. In association with the platinum metals, gold
Nickel ore mainly consists of coppernickel sulfide ore and nickel oxide ore, beneficiation and processing of both methods is completely different. Coppernickel sulfide ore beneficiation methods, the most important is the flotation, magnetic and reelection is usually secondary dressing method. ... Most gold ore now comes from either open pit ...

Platinum arsenide, sperrylite (PtAs2), is a major source of platinum associated with nickel ores in the Sudbury Basin deposit in Ontario, Canada. At Platinum, Alaska, about 17,000 kg (550,000 ozt) had been mined between 1927 and 1975. The mine ceased operations in 1990.

Natural Platinum is fairly impure. It is always associated with small amounts of other elements such as iron, gold, copper, and nickel, and may also contain the rare metals iridium, osmium, rhodium, and palladium. These impurities can lower its specific gravity to as much as 14, whereas pure elemental platinum is
One of the first major roadblocks that many people run into in Age 1 progression is finding ore. In SevTech: Ages, ore is controlled by a mod called Geolysys, and is not randomly distributed throughout the world like in vanilla Minecraft. Instead, the ore is aggregated into large veins of ore, where hundreds of ore may be located.

About 95% of all meteorites contain ironnickel (FeNi) metal. "Ironnickel" means that the metal is mostly iron but it contains 430% nickel as well as a few tenths of a percent cobalt. Ironnickel metal in meteorites also has high concentrations (by terrestrial standards) of rare metals like gold, platinum.
To know what type of rock is gold associated with you must see that the minerals most common in placer deposits are platinum, iridosmine, magnetite, iron pyrites, ilmenite, zircon, garnets, rutile and barytes; wolfram, scheelite, brookite and diamonds are less common. Diamonds are associated with gold in Brazil, and also occasionally in the Urals and in the United States.
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 nickelcopper ore of Sudbury, in Ontario.
Trace amounts of osmium also exist in nickelbearing ores found in the Sudbury, Ontario region along with other platinum group metals. Even though the quantity of platinum metals found in these ores is small, the large volume of nickel ores processed makes commercial recovery possible. Iridium
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 ...
