Technology Development and innovation can be a real source of competitive advantage within the copper industry. Mining industry typically spends between 0.1% and 1.0% of sales revenues on research and Technology Development. Phelps Dodge has a rich history of technological innovation.
The copper extraction process begins at an open cut mine where Copper Ore is blasted and removed via Excavators and Tip Trucks. The ore is fed to a Crusher where it is broken down to a specified maximum size and passed through to a conveyor.
Run-of-mine ore is crushed in batches in a single jaw crusher, with separate crushed ore storage for leach and float material. Gold doré and gold-copper concentrate are produced from the two circuits of the single processing plant. The float ore circuit comprises two-stage milling (SAG mill and ball mill) and conventional flotation.
The SAG mill had a 6–8% ball charge and the power consumption was 8 kWh/t, which agreed well with the expected value. 9.6. Problems. 9.1. In an SAG mill the dimensions of the mill were 9.75 m × 3.5 m and the specific gravities of the mineral and that of the balls charged were 4.1 and 7.9, respectively.
Mines are faced with numerous challenges, such as falling raw material prices, declining metal grades in the ores and higher energy prices. Especially because ore processing is particularly energy-intensive, the industry is again focusing on the saving of energy. This report shows what are the key energy saving considerations in the copper and gold mining sectors.
The process plant is designed to treat 55 million tonnes per annum of copper ore from Sentinel mine, with a separate 4 million tonnes per annum circuit designed to process nickel ore feed from the Enterprise project or additional copper ore feed from Sentinel. Technical Report. Trident's most recent NI 43-101 Technical Report.

Energy Efficiency in Copper Extraction 2008 Study 1-Purpose: • To provide a high level overview of specific energy consumption for copper extraction processes from ore in the ground to final salable cathode product (i.e. mining through electro -refining or electrowinning) to; – compare process routes,
General processing technologies for copper ore are summarized as below: I. Physical processing technology: Crushing & Grinding Solution. Flotation Process. II. Chemical processing technology: Leaching. 1. Flotation process are widely used for copper extraction. The ore pulp slurry is pumped to flotation cells for extracting.
with fresh ore by adding it to the SAG mill and ball mill feeds. After agitation leaching and gold extraction by RIP, water is recovered from the barren tailings in the tailings thickener. Part of the overflow from this thickener is passed through the SART plant (100 m 3/h), where dissolved copper and silver are recovered as a copper-silver ...
The leach–cementation process was seen to be a more cost-effective and simple to implement process at that particular time. This operation remained in place till late 1977. The process treated an average of 60 kt of the mill tailings containing about 0.2% copper per day, and recovered about 40% copper ( McKinney and Graves, 1977 ).

This equation is often used to determine the amount of water in a process stream1 knowing the solids concentration by weight and the tons/hr of solids in a process stream. Solids Concentration Example. The underflow stream from the classifying cyclone bank contains 100 tons/hour of ore which represents 45% of the total slurry mass.
