Magnetic separation definition usage working principle and

Magnetic separation is the main iron ore dressing methods. Common iron ore magnetite belongs to the strong magnetic minerals, hematite, limonite, specularite, siderite belong to weak magnetic minerals and so on, they are raw materials of iron and steel industry, our countrys iron ore grade is low, impurities content mostly is higher, therefore, more than 80 magnetic separation is needed.

RECOVERY OF ZINC FROM LEAD SLAG GLENCORE

RECOVERY OF ZINC FROM LEAD SLAG GLENCORE

A method for recovering zinc from slag derived from lead smelting comprises subjecting the slag to a leaching step under conditions in which zinc is dissolved into solution and silica present in the slag dissolves and re-precipitates in a form that is readily separable from liquid, and recovering zinc from the

Ferrosilicate slag from zinc production as aggregates

Ferrosilicate slag from zinc production as aggregates

ISF slag is a by-product, generated during the primary smelting of zinc ore in a form of blast furnace. It is a granulated, glassy material and has the appearance of dark coloured sand. It typically has a particle size distribution between coarse and fine sand, but a higher specific gravity than sand due to its metal content Figure 2.
