Originally published in NEW YORK–(BUSINESS WIRE)The Metals Company (Nasdaq: TMC), an explorer of lower-impact battery metals from seafloor polymetallic nodules, today announced that it derived an alloy comprised of high-grade battery metals from its pilot smelting campaign, conducted in partnership with Expert Process Solutions (XPS) with support from Hatch and Optimize Group.
Digital, innovation, technology, or operations teams were a good starting point when we first started looking to deploy complex process twins. My experience has however been that the most successful implementations are enabled by deep collaboration between digital and operations, maintenance, and production planning teams.
Pyrometallurgy is the subtle art and science of using high temperatures to process raw materials into valuable products. This is performed in several key stages, including pre-treatment, chemical reactions, separation of product and waste streams, and product refining. The interior of pyrometallurgical vessels in all stages is an extreme and ...

Non-ferrous metallurgical processing. Lime products play a key role in the mining and extraction of non-ferrous metals, including aluminum, copper, gold, nickel, cobalt, uranium, titanium and lithium. Lime is also important for the pyrometallurgical refining and smelting of several non-ferrous metals. In addition, lime products are used in ...
A hydrometallurgical process for recovering precious metals, such as gold, silver, selenium, and tellurium etc. from anode slime has been developed and tested successfully. The process comprises three major unit operations: leaching, liquid-liquid extraction, and reduction. The decopperized anode slime is first leached with nitric acid at an elevated temperature to obtain a leach solution ...

Pyrometallurgy Basic Principle. The basic premise of most pyrometallurgical operations is simple: high-temperature chemistry is employed to segregate valuable metals in one phase while rejecting gangue and impurities in another phase. In most instances, both phases are molten (such as the matte and slag in a conventional copper smelting operation).
