Recovery of Free Metallic Copper From the Grinding Circuit ...
The ore is basically ironstone consisting of up to 80% hematite, 10% magnetite and the balance silica. Copper head grade averages about 2% and gold 3 to 5 grams/tonne. Native (metallic) copper averages 20% of total copper. In particular ore types, the copper recovery by flotation is poor. This was believed to be due to the
Wills' Mineral Processing Technology | ScienceDirect
The grinding medium may be steel rods, balls, or rock itself. Although tumbling mills have been developed to a high degree of mechanical efficiency and reliability, they are extremely wasteful in terms of energy expended since the ore is mostly broken as a result of repeated, random impacts that break liberated as well as unliberated particles. Although the correct degree of liberation is .

Introduction to Mineral Processing or Beneficiation
· As the name implies, the grinding media in these mills are steel balls. The particles size of the feed usually does not exceed cm. The grinding is carried out by balls being carried up the side of the mill such that they release and fall to the point where they impact the ore particles in trailing bottom region of the slurry.
