Hydromet Technology Vale

This type of hydrometallurgical process is not entirely new. Many operations, some of them in Canada, have used hydrometallurgical processes for years for extraction of zinc and copper from sulphide concentrates. However, it was not until the 1990s that an acid-oxidative hydromet technology was developed to process nickel sulphide concentrates.

LEAD ZINC EXTRACTION PROCESSES EPrints

The lead bullion is refined using pyrometallurgical methods to remove any remaining nonlead materials (e.g., gold, silver, bismuth, zinc, and metal oxides such as oxides of antimony, arsenic, tin, and copper). The lead is refined in a cast-iron kettle in five stages. First, antimony, tin, and arsenic

Development of a hydrometallurgical process for the

20-03-2019  In order to recover gold and silver from anode slimes containing Cu, Ni, Sn, and Zn, an integrated hydrometallurgical process consisting of leaching, solvent extraction, and cementation was developed. All the metals together with 10% of Ag(I) were dissolved by the mixture of HCl and H2O2 at the optimum conditions.

Review of hydrometallurgical recovery of zinc from

01-08-2001  Anderson and Reinhart, 1979 used SX and precipitation method for the recovery of dissolved metals viz. zinc, copper, nickel and cadmium. Copper and nickel are extracted from the ammoniacal solution using LIX64N leaving cadmium and zinc in the raffinate. The cadmium and zinc are recovered from the raffinate as carbonates by ammonia distillation.

Hydrometallurgy Wikipedia

Hydrometallurgy is a technique within the field of extractive metallurgy, the obtaining of metals from their ores. Hydrometallurgy involve the use of aqueous solutions for the recovery of metals from ores, concentrates, and recycled or residual materials. Processing techniques that complement hydrometallurgy are pyrometallurgy, vapour metallurgy, and molten salt electrometallurgy.

Copper and Antimony Recovery from Electronic Waste by

A strategy for the efficient recovery of highly pure copper and antimony metals from electronic waste (e-waste) was implemented by the combination of hydrometallurgical and electrochemical processes. The focus is on copper recovery as the main component in the leached solution, whereas the antimony recovery process was established as a purification step in order to achieve a highly pure copper

Zinc Alloys: Properties, Processing and Applications

The zinc metal (which is 99.995% pure) can then be removed from the cathode and processed via methods such as zinc die casting. About 80% of global zinc production is via this hydrometallurgical process [4]. Zinc alloys are produced by mixing pure zinc with other metals in specific ratios.
