  • Copper Ore an overview | ScienceDirect Topics

    Flotation entails first attaching fine copper mineral particles to bubbles rising through an ore–water pulp and, second, collecting the copper minerals at the top of the pulp as a briefly stable mineral–water–air froth. Noncopper minerals do not attach to the rising bubbles; they are discarded as “tailings.” The selectivity of the process is controlled by chemical reagents added to

  • Flotation | ore dressing | Britannica

    Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process. This article was most recently revised and updated by Chelsey Parrott-Sheffer, Research Editor.

  • 60 Centuries of Copper: The Flotation Process

    The Flotation Process. Until quite recently copper ore had to be hand-picked if the extraction of the metal was to be economical. In fact, in the last century, ores of 4 percent grade were regarded as almost valueless. Today such ores (which would be regarded as relatively rich in copper) are scarce; the great majority of mines contain the metal in finely disseminated particles which aggregate

  • Copper Mining and Production Processes Explained

    The ore is enriched using a process called froth flotation. Unwanted material (called gangue) sinks to the bottom and is removed. Roasting. This is where the chemical reactions start. The powdered, enriched ore is heated in air between 500°C and 700°C to remove some sulphur and dry the ore, which is still a solid called calcine. Smelting with fluxes. A flux is a substance which is added to

  • Copper Mining and Extraction: Oxide Ores

    The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining. The smelting stage gives the name pyroprocessing

  • Copper Mining and Extraction Sulfide Ores

    From the formula, it is clear that iron and sulfur have to be removed in order to produce copper. The roasting process: changes some of the CuFeS 2 to copper oxide; removes some of the sulfur as sulfur dioxide; This is done by heating the concentrated ore from froth flotation. It is heated to between 500 °C and 700 °C in air. The product from

  • pH/ORP measurement Copper flotation process

    The flotation process can separate a required mineral such as copper, nickel, molybdenum or zinc from ore. Flotation can separate this mineral from waste materials or from another mineral. The process starts with crushed ore. A ball mill receives the crushed ore and reduces its particle size to the consistency of sand. Next, the ground ore from the mill travels as a high solid slurry to a

  • A Multistage Sulphidisation Flotation Procedure for a Low

    For the flotation process, the two most common approaches are controlled potential sulphidisation (CPS) and the fatty acid flotation method [1]. Heap leaching involves trickling dilute sulphuric acid over a heap of copper ore, to form a pregnant copper sulphate solution. Copper is subsequently extracted from the solution using solvent extraction and electrowinning technologies. Froth flotation
