Ores belong to mineral aggregates. Under modern technological and economic conditions, metals or other products can be processed and extracted from minerals on an industrial scale, which can be divided into metal ores and non-metallic ores. The ratio of the weight of the useful component (element or mineral) in the ore to the weight of the ore is called the ore grade, which is one of the most important indicators to measure the ore. For a large volume of goods, small quality differences can make a huge difference in value.
Ores are generally divided into the following categories:
One, metal ore
1. Iron ore: iron ore for blast furnace charge, iron ore for direct reduction charge, acid iron pellet for blast furnace, etc
2. Manganese ore: manganese tetroxide with soft magnetic ferrite, manganese ore with metallurgy, manganese carbonate ore powder, manganese dioxide ore powder with chemical industry, etc
3. Chromium ore: chromium ore for refractory materials, metallurgical chromium ore, vanadium-bearing titanium slag, acid-soluble titanium slag, etc
4 Light metal ore detection: tin concentrate, lead concentrate, titanium concentrate (rock ore), lapis lazuli ore, bauxite ore, mixed lead-zinc concentrate, magnesia, etc
5. Heavy metal ore: copper ore, lead ore and zinc ore, cobalt ore, nickel ore, tin ore, antimony ore, bismuth ore, borax ore, copper concentrate, antimony concentrate, cobalt concentrate, etc
6. Dilute metal ore: Tungsten ore, molybdenum ore, lithium ore, rubidium ore, cesium ore, beryllium ore, tantalum ore, niobium ore, zirconium ore, rare earth ore, ferrotantalum, ferroniobium concentrate, copper slag concentrate, high rare earth iron ore, cerium lanthanite concentrate, monazite concentrate, yttrium phosphate concentrate, rare earth rich slag, tungsten concentrate, molybdenum concentrate, beryllium concentrate, beryl, beryl concentrate, high titanium slag, tantalum concentrate, etc
7. Precious metal ore: gold ore, gold concentrate, gold carrying carbon, metallurgical bullion ore, silver concentrate, etc
Two, non-metallic ore
1. Chemical raw material ore: phosphate ore and phosphorus concentrate, pyrite and sulfur concentrate, realgar ore, gynoecious ore, arsenic ore, borax ore, alum ore, lapis lazis ore, serpentine ore, boraxite ore, alum ore, barite, import and export fluorspar powder, sulfur concentrate, etc
2. Metallurgical auxiliary minerals: fluorite, limestone, dolomite, metallurgical lime, flake graphite, sintered corundum, pre-fused calcium aluminate for steelmaking, pre-fused calcium ferrite for metallurgy, high bauxite clinker, light fired magnesium oxide, hard clay clinker, magnesite, fused magnesite, etc
3. Building materials and minerals: silicate rock, limestone, chemical limestone, dry ground mica powder, wet ground mica powder, plate glass with feldspar, feldspar, chlorite, talc, saponite, pyrophyllite, glass industry with quartz sand, silica, granite, etc
4. Other non-metallic minerals: bauxite, ferrivanadite, diamond, natural diamond, jewelry jade, jade, pearl, cryolite, sepiolite, etc
