In another preferred embodiment, the initial grinding of the slag is carried out as a semiautogenous grinding operation and leads to a fairly coarse pulp although suitable for flotation in a unit cell with an appropriate frother and collector. Typically, the grinding proceeds until about 80% of the pulp passes a 100 mesh screen.

I301 I302 INTRODUCTION The Mount Isa Copper Concentrator grinding circuit currently consists of two 32' x 16' semiautogenous (SAG) mills, each powered by two MW motors, followed by two 16'6" x 20' ball mills powered by (1) MW motors.

 · Autogenous grinding is favored when the ore is quite competent and a fine grind is required. Semiautogenous grinding is applied when fine crushing could cause severe problems or when ore is variable in hardness or competency. Figure 2 shows a typical conventional crushinggrinding circuit with three stages of crushing followed by ball mills or ...

 · Keywords: slag, copper, slow cooling, nonstationary cooling ... blister in processing concentrate by using autogenous flash smelting technology, ... and impossibility of separating a phase rich in copper before grinding. Other method is slow cooling of slag in pots.

 · Since SAG represents a combination of autogenous and ball milling, a better understanding of the mechanism of the comminution process in a SAG mill can be obtained by examining first the information available on autogenous grinding. In an interesting study of autogenous grinding in a 10ft. dia. x 2ft. long Cascade mill:

 · Abstract The temperature dependences of the viscosity of the slags of the autogenous smelting of copper–zinc concentrates have been determined. The activation energies of viscous flow and the temperature of the onset of solidifiion of the molten slags are calculated. The influence of the suspension (magnetite) and emulsion (matte) components on .

 · Thornton (1973) reported that in pilot plant studies with a copper–lead–zinc ore, copper floatability was improved by switching from mild steel grinding to fully autogenous grinding. His research indied that aeration of pulps after grinding in a mild steel mill followed by flotation gave close to the same metallurgical results as grinding in a ceramic mill followed .

Grinding is one of the most expensive unit operations. The cost of grinding media is the most expensive item in grinding costs. Therefore, it is only reasonable to attack the costcutting area by trying to reduce the consumption of media. This introduces the field of autogenous or rockonrock grinding is not new to us.
