9 Ore Deposits and Economic Minerals – Mineralogy

+

The best metal ore minerals are those that contain large amounts of metals of value. Most metallic ore minerals are native elements, sulfides, sulfosalts, oxides, or hydroxides. Ore deposits are highly variable in nature and origin. The most important kinds of ore deposits are magmatic, hydrothermal, or sedimentary. Mineral Commodities Mineral Resources. Earth gives us many ...

refining of platinum group metals ore concentrate. pgm ore concentrate The figure below shows a typical assay of a South African platinum group metals ore concentrate obtained as the filter cake after sulfuric acid leach (according to the Sherrit process) of a Merensky reef converter matte. In fact the Sherrit process results in two completely different behaving concentrates which are blended ...

Extraction of Metals from Ores – Different Processes Involved

Extraction of Metals from Ores – Different Processes Involved

+

The conventional metal extraction processes will be discussed elaborately on this concept page. The simpler the process, the better and more costeffective it is for the industries to extract metals from their ores. It all depends on the principles of metallurgy we use to check the inorganic chemical properties of the constituents of an ore. This is how an extraction process is designed. Every ...

Leaching

Leaching

+

The preprocessing of ore before leaching involves the grinding and roasting of the ore. Roasting is done to remove the carbonaceous elements trapped inside the ore. After preprocessing, the ore is leached with acid of alkali solutions to extract the metal. Heap leaching is carried out in the extraction of copper, nickel, uranium and precious metals.

 · Hyperaccumulator plants may contain valuable metals at concentrations comparable to those of conventional metal ore and can be significantly upgraded by incineration. There is an incentive to recover these metals as products to partially counterbalance the cost of disposing the contaminated biomass from contaminated soils, mine tailings, and processing wastes. Metal recovery is included in ...

Sometimes, leaching can be performed by microbes, a process that is an attractive and profitable process for the dissolution of metals from laterite ore. Microbebased leaching is often the preference when typical mining approaches are ineffective or too expensive. Such treatments have offered access to copper, gold, lead, nickel, and zinc.

 · Introduction• Hydrometallurgy is a metal processing technology that uses a chemical process combining water, oxygen or other substances in a pressurized or other vessel to dissolve a metal from its ore, concentrate or an intermediate product . Further processing is required to produce high purity metal.[1] 3 4. Process Stages• Hydrometallurgy is typically divided into three general .

The process of extracting a metal from its ore and refining it, is called metallurgical process or simply as metallurgy. The actual process of extraction of a metal from its ore depends upon the nature of the ore and the metal. There is no universally operational method for the extraction of metals. Certain common steps however, are involved in all metallurgical processes. Steps involved in a ...

A common activity of precious metal ore processing is the analysis of the Au concentrations on activated carbon. This is a critical measure on the efficiency of the carbon in pulp (CIP) and carbon in leach (CIL) processes. By measuring the gold in the stripping solution, operators can quickly and easily determine when the solution will be barren of gold, significantly improving the plant's ...

Platinum Processes Uses. A solid platinum nugget. Image from Nuggets or grains of pure platinum can be found in nature, but more frequently, platinum is found alloyed with other metals, such as iron, copper, gold, nickel, and the other size of platinum grains or nuggets varies from small granules to pebbles weighing up to 20 pounds (9 kg) or more.

Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source. Silicon (Si) is a semimetallic or metalloid, because it has several of the metallic characteristics. Silicon is never found in its natural state, but rather in combination with oxygen as the silie ion SiO 4 4 in silicarich ...
