Description

Slimes And Sludges, Cobalt Refining CAS NO 121053-29-0 are intermediate by-products generated during the hydrometallurgical processing and refining of cobalt ores and concentrates. This material is of critical importance as a secondary resource for the recovery of valuable cobalt and associated metals, contributing to supply chain security and circular economy principles within the metals industry. It is primarily required by cobalt refineries, battery material producers, and metal recycling facilities seeking to optimize yield and process efficiency.

Application

• Cobalt Recovery and Reprocessing: As a primary feedstock for the secondary extraction and purification of cobalt metal and salts.
• Battery Material Production: Serves as a source of cobalt for the synthesis of precursors for lithium-ion battery cathodes, such as NMC (Nickel Manganese Cobalt Oxide).
• Alloy Manufacturing: Recovery of cobalt for use in the production of high-performance superalloys, magnetic alloys, and hard-facing alloys.
• Catalyst Production: Source material for the manufacture of cobalt-based catalysts used in petroleum refining, chemical synthesis, and automotive exhaust systems.
• Pigment and Dye Industry: Provides cobalt for the production of blue ceramic glazes, glass colorants, and pigments (cobalt blue).
• Metal Recycling Operations: Integral to urban mining processes for recovering cobalt from complex electronic and industrial waste streams.
• Feedstock for Chemical Synthesis: Used in the production of various cobalt compounds, including cobalt sulfate, cobalt chloride, and cobalt carbonate.
