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 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

Q&A


What are the preparations for testing industrial mines?

(1) Communicate with customers and understand their needs;

(2) Product testing standards and procedures;

(3) Project and plan to protect harmful substances and prepare for formal testing.

What are the analysis and testing items?

(1) Composition analysis: phase analysis, rock analysis, clay analysis

(2) Element analysis: natural collection of unknown samples analysis, chemical analysis

(3) Ore grade: light slice identification, microphotography, rock identification

(4) rock and mineral physical test: moisture, alkali, acid, true density, volume resistance, surface resistance, transparency, gloss, Shore hardness, Mohs hardness; Refractive index, voidage (mercury injection, adsorption, total porosity, obturator), specific surface area (ethylene glycol, breathable, nitrogen)

What are the key detection parameters of ore?

The key test parameters of ore include modulus, expansion amount, expansion stress, collapse resistance index, firmness coefficient, compressive strength, tensile strength, shear strength, Prinell hardness, Mohs hardness, water content, bulk density, specific gravity, water absorption, saturated water absorption, porosity, rock and ore identification, mineral composition analysis, element content, ash detection, particle size, etc.

What is done after testing?

Collate test data, issue professional quality inspection reports, collate and archive key points in the test process.
