The industry-leading hydrometallurgical process ensures nickel and cobalt recovery in excess of 90%, high-quality product standards, low-cost production, and is in use worldwide.
Some metals, such as copper and gold, can be processed from crushed ore or concentrated minerals to purified metal using hydrometallurgy. The basic processing steps include extraction, concentration/purification, and recovery.
Hydrometallurgy provides for a more direct metal-recovery route, reducing working capital and enabling new methods that can recover metals now in scarce supply. Through research and development, hydrometallurgical processing has made steady progress.
Processing of secondary zinc raw materials and recycling of zinc are increasingly important. Outotec has designed a hydrometallurgical process to produce Special High Grade zinc from fume oxides of e.g. Ausmelt TSL and Waelz furnaces. The process includes washing and leaching stages and, in case of raw materials with high chloride and
We have over 40 years of experience in hydrometallurgical processes. Our capabilities and offerings cover everything from process testing and flowsheet development to plant design and proprietary equipment supply for the hydrometallurgical processing.
Hydrometallurgy is a method of processing metals via aqueous solutions. Hydrometallurgical processes all share the characteristic of having the metal dissolved in water, but each process is tailored to the materials. Therefore, they don't necessarily resemble each other beyond that …
We have several processing alternatives for nickel and cobalt raw materials, ranging from pyrometallurgical to hydrometallurgical approaches.
Leading cost effective solutions for hydrometallurgical treatment - we have delivered a diverse array of hydrometallurgy and refining projects across the globe, particularly in the areas of gold, uranium and copper.
Hydrometallurgy is the science of moving metal ions from a feed source (such as a mined ore body, concentrates, intermediate residues or recycled metallic feedstock including batteries) into aqueous solution. The valuable elements are recovered from solution as either intermediate or final saleable products produced using aqueous chemistry.
In this chapter, the processes of hydrometallurgical extraction, concentration/purification, and recovery will be discussed based on hydrometallurgical fundamentals and their application to copper, gold, and zinc processing.
