Jun 23, 2013· Reagent costs are typicallyaround 10% of the milling costs on a large copper mine, butenergy costs may contribute well over 25% of these costs. Grinding is by far the greatest energy consumer and this processundoubtedly has the greatest influence on metallurgicalefficiency. Grinding is essential for liberation of the mineral in theassembly, but ...

Although basic porphyry copper flotation and metallurgy has remained virtually the same for many years, the processing equipment as well as design of the mills has continually been improved to increase production while reducing operating and maintenance costs. Also, considerable attention is paid to automatic sensing devices and automatic controls in order to assure maximum metallurgy and ...
1 Over the past 15 years, mine-to-mill studies have focused attention on the impact blast fragmentation has on concentrator throughput. Blasting provides the first opportunity for comminution – or size reduction. It is also a cheaper and more efficient process, compared to both crushing and grinding.
The copper minerals and waste rock are separated at the mill using froth flotation. The copper ore slurry from the grinding mills is mixed with milk of lime (simply water and ground-up limestone) to give a basic pH, pine oil (yes, it comes from trees -- a by-product of paper mills) to make bubbles, an alcohol to strengthen the bubbles, and a ...

Operating costs are the physical costs of pro-ducing copper: the direct and indirect costs in-curred in mining, concentrating, smelting, and refining copper. They include transportation to the mill, smelter, and refinery, and metallurgical processing of the byproducts. Some estimates of operating costs also include the freight charges

Ma-chinability index ratings have therefore been added to the tables included in the handbook. Machinability ratings
The copper flotation step is inherently inefficient for cobalt, with recoveries typically from 40% for oxides up to 80% for sulphides, so there is a substantial amount of cobalt contained in tailings dams that could be recovered – e.g. the Kolwezi Tailings Project.

This chapter briefly describes the technology for producing copper, from exploration, through mining and milling, to smelting and refining or
Estimated Water Requirements for the Conventional Flotation of Copper Ores . By Donald I. Bleiwas . Introduction . This report provides a perspective on the amount of water used by a conventional copper flotation plant, including the makeup water required to compensate for water losses. Much of the global
Scavengers provide a final, strong flotation treatment for the rougher tailings by using a strong concentration of reagents and vigorous flotation to recover as much of the remaining sulfide minerals as possible. The float from the scavenger flotation is often recycled through a regrinding mill and sent back to the rougher flotation cells.

Our capital costs are actual list prices or reliable approximations. Our operating costs are solid engineering estimates. If you have confidence in your equipment selection procedures, you and others will have confidence in your cost estimates - if you rely on Mine & Mill Equipment Costs - .
Flotation of non-sulfide copper minerals is rare because these ores are mostly subjected to hydrometallurgical copper recovery, for example, heap leaching. In Zambia and Zaire, however, siliceous copper oxide ores are floated with fatty acid collectors, and dolomitic copper oxide ores are sulfidized with sodium hydrogensulfide and then floated ...
Application Note pH Control in Copper Flotation for Maximized Product Yield Background Copper ore may be separated from crude ore using a flotation pro-cess that takes advantage of the physical (as opposed to chemical) properties of small copper ore particles. To maximize the copper yield, pH control is necessary in the flotation tanks.
1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air .
Surface/underground mine cost models - a variety of sizes/types: theoretical mining operations, flotation milling, carbon-in-pulp, heap leach & placer models.
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
Copper Sulfide Flotation Reagents. Lime is added to the Ball Mill by a Cone Type Dry Reagent Feeder. Other reagents, such as cyanide, xanthate, and a frother are fed and controlled by No. 12A Wet Reagent Feeders to the classifier and to the conditioner ahead of flotation. Sampling. Automatic Samplers are provided for the sampling requirements.
Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.
