Froth floatation method is commonly used for the concentration of the low-grade sulphide ore. The principal is based on the fact that gangue and ore particles have a different degree of wettability with water and pine oil. The ore particles are wetted by oil whereas gangue particles are wetted by water.

What is Concentration? Concentrating ore is a method of removing gangue particles and other impurities. Alternative names for ore concentration include ore-dressing and benefaction. The procedure of ore concentration is a critical stage in obtaining pure metal from ore. Separating ore from gangue particles is required for metal extraction.

where E is the criterion index for the concentration criterion of ore.ρ 1 ′ and ρ 1 are, respectively, the density of high-density and low-density minerals in ores to be separated. ρ is the density of the mediums. When E > 2.50, the separation can be easily conducted, and the lower limit of the effective separating particle size can reach 0.019 mm.

Concentrate is a product which is the result of concentration of the ore/seed, in this case is meant copper containing approximately 30% copper, but also contains high grade gold and silver. The gold content varies between 20 - 70 ppm, while silver is about 60 - 100 ppm. Preparation of concentrate sample is drilling and blasting to
