PGMs beautiful color.strong scalability; refractory, abrasion resistance, corrosion resistance; chemically stable at high temperatures. Therefore, they have a wide range of uses. In platinum group metals, the most familiar, the most used is platinum. It is even more rare and valuable than precious metals gold and silver.

Pure platinum silver-white; with a metallic luster. Platinum color and luster is naturalness, frozen in time. Hardness of 4 to 4.5 degrees. Relative density of 21.45, the proportion of 15 to 19 or 21.4. Ductility, and can be pulled into a very fine platinum wire, rolled into very thin platinum foil; strength and toughness, but also much higher than other precious metals. 1 gram platinum even pulled into a 1.6 km long filaments, it will not break. Melting point up to 1773.5 ℃. Good thermal conductivity. Extremely chemically stable, insoluble in acid and alkali, does not oxidize in air. Platinum silver does not absorb water, and has a unique catalysis.

Platinum group elements including ruthenium, rhodium, palladium and six elements osmium, iridium, platinum. Affinity affinity with sulfur and iron deficiency, iron deficiency dependent on their parents affinity to sulfur. Sulfur, arsenic, tellurium, bismuth and other elements on the enrichment of platinum group elements mineralization play an important role.

Platinum mines and basic, ultrabasic rocks about. Platinum ore body can be formed in the basic, ultrabasic rocks being, it may be formed in the basic, ultrabasic rocks of the contact zone or fault.

Platinum group elements in the ore content is low, the mineral particle size small, the naked eye is generally difficult to identify. Therefore, look for platinum mines shall be based on geological characteristics and prospecting mark on the possible location of a platinum-containing, by picking a block or channel sampling, assaying carried out spectroscopic or chemical analysis to determine its content.

Sand platinum deposits are mainly distributed in the basic, ultrabasic rocks area, containing mineral ore or rock formed by weathering decomposition. There are residual, talus, alluvial and other type, alluvial placer industrial significance of larger, higher grade, often concentrated in the lower part of the bedrock surface alluvial sand. The main platinum group minerals are crude platinum ore, natural osmium, natural iridium, osmium iridium ore, iridium, osmium ore, often accompanied by gold (sand platinum mines are often the primary ore minerals to natural elements formed mainly by the more valuable as placer chromite type ultrabasic rocks PGE deposits formation is good. some of the original ore mining platinum group metal does not have value in the vicinity of the low-lying river valley and modern richer placer is formed. placer is looking for signs of primary ore).
