grinding. The ore must be ground to a particle size sufficiently close to the grain size of the iron-bearing mineral to allow for a high degree of mineral liberation. Most of the taconite used today requires very fine grinding. Prior to grinding, the ore is dry-crushed in up to six stages, depending on the hardness of the ore.

May 29, 2009 Grinding Process. The grinding wheel consists of several abrasive particles which act as minute cutting edges, and these particles are bonded with the help of bonding material. The advantage of using such a process over conventional metal removal processes are as follows. The rate of removal of material is much higher than, say, a traditional file
In order to maintain a stable assay process, the analytic part of the system must be kept in control as well as the sampling and preparation part. One way of monitoring the performance of the analytic system is to systematically assay standard material whose sampling characteristics are carefully controlled.
