The mill scale contains high amounts of Fe and low amounts of silica and alumina. Thus, recycling it through the sintering process helps in the saving of raw materials like iron ore and limestone. This paper presents preliminary findings of a study that investigates the potential for recycling steel mill scale in the sintering process.

The mill is the most power intensive element in a grinding mill circuit and the power draw of the mill motor is represented by P mill (Matthews and Craig, 2013). The slurry mixture of ground ore and water in the mill is discharged into the sump through an end-discharge screen that limits the particle size of the discharged slurry.

The Mexican arrastra (also "rastra" or "arastra") was the earliest type used during the California Gold Rush in the 1850s. Simply constructed, these devices consisted of a flat track of stone inside a low wall of rock or wood forming a basin to hold the ore, and center post and horizontal shaft made of wood (often just a small tree trunks).

A hybrid non-linear model predictive controller (HNMPC) is developed for a run-of-mine ore grinding mill circuit. A continuous-time grinding mill circuit model is presented with a hydrocyclone cluster as the primary classifier. The discrete-time component is the switching of hydrocyclones in the hydrocyclone cluster.
