The chemical formula of niobium-iron ore-tantalite is AB2O6, both of which are referred to as niobium-tantalum. Where A in the formula stands for iron and manganese, and B stands for niobium and tantalum. The magnetization rate of niobium-iron ore-tantalite is (22.1 to 37.2) × 10-6. The dielectric coefficient of niobium-iron ore is 10 to 12 ...
Looking at post-beneficiation phosphate rock concentrate, the average grade of global capacity declined from 32.5% P 2 O 5 in 1983 to 30.1% P 2 O 5 in 2013. The global average was less affected by the tonnage changes in the US and China than was the case for the ore values because, for both producers, their concentrate grades …
This paper proposes a new enrichment method of medium–low grade phosphate ore with high silicon content via nitric acid leaching, separation and re-precipitation in sequence. The nitric acid leaching and the precipitation of the leaching solution were investigated and the P 2 O 5 recovery reached 99.82%. The phosphorus …

Beneficiation, also known as mineral dressing or ore processing, may involve a variety of operations such as size reduction, size separation, mineral separation, dewatering, and thermal processing. Almost all phosphate ores require beneficiation to meet commercial specifications concerning particle size, moisture content, or chemical …
For grinding phosphate rock, the energy used is about 25-35 MJ per tonne and the process water needed is around 13 m3 per tonne while the average values for ore flotation units are 62.5 MJ per tonne and 5.3 m3 per ton [31] for energy and water use, respectively. So far the challenge in the flotation of high carbonate containing …
Flotation is still regarded as the main processing method in phosphate ore beneficiation for a certain time in near future. The world is rich in phosphate resources, but the vast majority of the resources are of middle and low grade ores, and it is difficult to obtain high grade concentrate at a high recovery by using traditional separation ...
