GRINDING

Mill Capacity: 1950 TPD

The milling/Grinding process of gold ore in Hutti employs two distinct grinding techniques.

In the first technique grinding is done in two stages i.e. one primary mill and 3 nos. of secondary tube mills constitute one stream of grinding. Two such streams are there. The discharge of these mills are passed on strake table spread with blankets which recover coarse gold by gravity process, and the system is in close circuit operation.

In the second technique, single stage grinding is done in four nos. of independent ball mills in close circuit with cyclone classification system. The mill discharge is passed through knelson concentrators to recover the free gold. The stake tables concentrate and knelson concentrate is further upgraded on James table to produce smelt able grade of gold.
