Copper-nickel sulfide ores are one of the main sources platinum. One ways to extract precious metals from such involves melting a concentrate in electric ore smelting furnaces, where melt is divided into matte and slag. Platinum generally concentrated matte; however, some it remains slag, thus leading metal losses. In order reduce platinum losses, forms these phases should be studied. It was fo...

Two liquid phases: molton metal (or alloy) and slag occur in most metallurgical systems. The slag occurring at the surface of the metal bath not only protects it against negative atmospheric effects but also enables to make many treatments necessary to achieve good quality of the material designed for shaping the casted products. In the conditions of fully controlled process (e.g. melting or re...

This slag is generally recycled in a waste recycling plant (WRP) so as to separate the magnetic and the nonmagnetic portions by means of mechanical crushing and magnetic separation. The magnetic portion is then recycled and used in the primary steel making p...

Mold powders are fluxing agents used as raw materials in the steel industry, which play very important role in processing stability and final surface quality of a product. Surface quality depends particularly on the viscosity and the heat transfer of infiltrated mold flux between the mold wall and the solidified steel shell. Heat flux across the interfacial gap depends on thermal properties of ...

Copper slag is a hard material produced from smelting copper-bearing ores. Over the years, research has prioritized utilizing as secondary source of base metals. This paper focuses on grinding/milling copper collected BCL Mine in Botswana to obtain maximum amount desired size class with minimal energy consumption. will then be followed by an integrated flotation and leaching approach recover co...
