Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore.Slag is usually a mixture of metal oxides and silicon dioxide.However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also serve other purposes, such as assisting in the temperature control of ...
The slow cooing of slag results in a higher phosphorus and manganese in rich phase. Moreover, phase size grows by slow cooing in the simulated slag. The author confirmed that the magnetic properties of each others phase are significantly different; it is possible to separate phosphorus and manganese by magnetic separation process.

Gravity and magnetic separation methods were unsuccessful but in 1901 a new metallurgical process, called flotation, was devised at Broken Hill which achieved recoveries of the zinc minerals from ore upwards of 60%. After considerable experimentation, a selective flotation method which worked on a commercial scale was perfected in 1912.
