Copper Production. W.G. Davenport, in Encyclopedia of Materials: Science and Technology, 2001 1.1 Physical Beneficiation. Beneficiation of copper ores is done almost exclusively by selective froth flotation. Flotation entails first attaching fine copper mineral particles to bubbles rising through an ore–water pulp and, second, collecting the copper …

Mineral Beneficiation. What is mineral beneficiation? Mineral beneficiation is a process by which valuable constituents of an ore are concentrated by means of a physical separation process. As one of the initial steps of extractive metallurgy, the main purpose is to prepare the ore prior to downstream purification processes.

Hence, this analysis will focus on selecting Bond Index values and comparing different cost allocation systems, using: 1) metal market prices, 2) data from the Ecoinvent database, and 3) a thermodynamic allocation procedure explained below. When the ore grade is very low, the comminution stage has the highest share of energy consumption.
