In this paper, the beneficiation of rejected phosphate washing sludges (Ps) was investigated using acid leaching methods. Chemical analysis showed that these sludges are a low-grade ore (15.84% P2O5).
5 Acid leaching. Acid leaching is the use of quartz insoluble in acid (except HF), other impurity minerals can be dissolved by acid, further purification of quartz. Acids commonly used for acid leaching include sulfuric acid, hydrochloric acid, nitric acid and hydrofluoric acid; and reducing agents include sulfurous acid and salts thereof.

There are two ways of leaching: air agitation and mechanical agitation. Because of the small particle size and sufficient agitation, the agitation leaching process has a faster leaching speed and higher recovery rate than the pool leaching process. Therefore, the agitation leaching process can treat high-graded ore or the ore with lower-graded ...
The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making. With the high-grade ores depleting very fast, the focus is on the beneficiation of low-grade resources. However, most of these ores do not respond well to the conventional …
Gold Heap Leaching Production Line; Alluvial Gold Mining Production Line; Related Cases. ... Introduction to the Technological Process of Cambodia Gold Mine Flotation Project(400t/d) Gold copper ore：Four commonly used beneficiation methods; Equipment model of 300 ton gold mine flotation plant;
In a typical continuous single or multistage leaching process, the stream containing the solid phase is called the underflow whilst the solute-rich stream is referred to as the overflow stream. Equilibrium in a solid-liquid stream is established when the concentration of solute in the underflow and overflow streams leaving a stage are equal.
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 …
The gold leaching( carbon in leach) process has been widely used in newly built gold leaching plants in recent years, and many plants are changing into CIL as well.The gold-leaching CIL process is suitable for treating oxidized gold ore with low sulfur and mud content.It is unsuitable for the gold ore with high-grade silver. Generally, the proportion …
[Introduction]: Gold CIL process (carbon in leach) is an efficient method of extracting and recovering gold from its ore.By cyaniding and carbon leaching crushed gold ore slurry simultaneously, the CIL process …
