Beneficiation of nickeliferous laterite by reduction ...

01/05/2012  Ni beneficiation of laterite ore by using direct reduction process is proposed. Sodium sulfate is capable of intensifying the reduction roasting of laterite. Average particle size of ferronickel grows up to 50 μm when reduced with Na 2 SO 4. Selective enrichment of Ni can be realized by suppressing the metallization of Fe. New-born troilite (FeS) facilitates the aggregation of ferronickel ...

Phosphate ore is a valuable strategic resource. Most phosphate ore in China is collophane. Utilization of mid-low grade collophane is necessary to maintain social sustainable development. The gravity-flotation combination separation process can be utilized to separate mid-low grade collophane, but the process consumes a large quantity of acid in the reverse stage. Sodium dodecyl sulfate (SDS ...

Chromite ore beneficiation - Idaho Research Foundation, Inc.

Sodium sulfate, Na 2 SO 4, was also added in varying amounts ranging from none to 20 parts by Na 2 SO 4 per 50 parts chromite ore (by weight). The pulverized chromite ore and any additions were pressed into cylindrical pellets having an approximately 1.5 centimeter diameter using axial pressure in the range of 20,000-30,000 pounds per square inch.

Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate, the beneficiation of the low-grade phosphate ore is, hence, of great necessity.

Sodium sulfide - Wikipedia

Sodium sulfide is the chemical compound with the formula Na 2 S, or more commonly its hydrate Na 2 S9H 2 O.Both the anhydrous and the hydrated salts are colorless solids. They are water-soluble, giving strongly alkaline solutions. When exposed to moist air, Na 2 S and its hydrates emit hydrogen sulfide, which smells like rotten eggs.Some commercial samples are specified as Na 2 SxH 2 O ...
