Copper Concentrate Thickening and Filtering. The final cleaned flotation concentrate flows or is pumped to a Spiral Rake Thickener. A Adjustable Stroke Diaphragm Pump, mounted on the thickener superstructure, meters the thickened concentrate to the Disc Filter. The Thickeners are often used to store concentrates for filtration at fixed intervals.

Copper extraction - Wikipedia
Copper concentrates produced by mines are sold to smelters and refiners who treat the ore and refine the copper and charge for this service via treatment charges (TCs) and refining charges (RCs). The TCs are charged in US$ per tonne of concentrate treated and RCs are charged in cents per pound treated, denominated in US dollars, with benchmark prices set annually by major Japanese smelters.

Evaluating Copper Rougher-Scavenger Flotation …
A modal examination of the products produced by the copper flotation rougher-scavenger circuit reveal important information regarding the limits to the efficiency of the process, imposed by mineralogy, fragmentation and flotation capacity. Let’s discusses various aspects of rougher flotation circuit performance and how to evaluate its results .
Acid Leaching Copper Flotation Concentrate
As an alternative to Acid Leaching, Copper Chalcopyrite (CuFeS2) concentrates are processed traditionally by smelting, which results in sulfur dioxide (SO2) emissions. The development of a hydrometallurgical process for recovery of metals from concentrates of Cu ores offers industry a low-cost, low-pollution alternative to the traditional pyrometallurgical practices.
Innovations in Copper Mineral Processing Technology
Reasons for Copper Ore Sorting • Pre-concentrate ore at mine: – Removes low-grade fraction that is uneconomic to process. – Reduces haulage costs. – Reduces grinding energy and flotation reagent costs. – Improves metal recoveries. • Monitor the mill feed which provides real time data to operators for process optimization.
