This technology is applicable to the recovery of nickel, cobalt, copper, and platinum group metals from furnace or converter slags emanating from copper or nickel smelters treating sulphide concentrates. Pilot-plant testwork at Mintek has demonstrated recoveries of 98 for nickel and over 80 for cobalt, at power levels of up to 600 kW.

Management Of Copper Pyrometallurgical Slags Giving

Some properties of a typical copper slag are shown in Table I, and it can be observed that air-cooled copper slag has a black colour and glassy appearance. The specific gravity varies with iron content, from 2.8 to 3.8. The unit weight of copper slag is somewhat higher than that of conventional aggregate. The absorption capacity of the

Process Of Preventing As Elution From Copper Slag

A process of water-granulating copper smelting slag can readily suppress elution of As from the copper smelting slag. A process of water-granulating a copper smelting slag with granulation water in a circulating system, includes granulating the copper smelting slag with the granulation water settling suspended solids from the granulation water circulating in the system in a settling tank ...

Preface For Thematic Section Slag Granulation Springerlink

May 31, 2019 Granulation of molten metallurgical slags is a value-adding process that converts a low-value byproduct and sometimes waste into a saleable product with multiple uses by the building and construction industries. In particular, when ironmaking slag is granulated and is substituted for Portland Cement, the environmental and economic benefits ...
