The main aim of laboratory tests was to find a relation between lithology of tested samples of ore and grinding media wear. Wear tests were performed in a laboratory mill filled with ball grinding media. Wet grinding was performed, which is typical for copper ore milling. Details of equipment used and tests data are presented Table 3.
The next step is to feed the crushed ore into a wet grinding process in tumbling mills. These mills contain the ore, water and steel balls and further reduce the particles to the optimum size for the flotation process which follows. About 80% of copper from ore is generated using flotation, smelting and refining.

A VSI mill throws rock or ore particles against a wear plate by slinging them from a spinning center that rotates on a vertical shaft. This type of mill uses the same principle as a VSI crusher.. Tower mill. Tower mills, often called vertical mills, stirred mills or regrind mills, are a more efficient means of grinding material at smaller particle sizes, and can be used after ball mills in a ...

We are a professional mechanical equipment manufacturer, we provide original parts, service solutions, extensive training and extensive wear, crushing chambers and screening media solutions to reduce operating costs, improve product quality and maximum productivity.
GRINDING COPPER ORE Although a clean rougher tailing can often be achieved at 65-mesh the copper mineral is not liberated sufficiently to make a high grade copper concentrate, thus some form of regrinding is necessary on the rougher flotation copper concentrate It is not unusual to grind the rougher flotation concentrate to minus 200-mesh.
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 .
The laborious task of mining copper ore by hand made it difficult to obtain large quantities for production. During the Industrial Revolution, coal- and steam-powered machinery paved the way for a huge increase in copper production with mines smelting between 200 and 300 tons of copper ore .
Stage 1: Crushing and grinding The ore from the mine contains about 2% copper. To get at the copper the first stage is crushing in huge cylindrical ball mills. Ball mills crush the ore into a fine powder. (Courtesy of Rio Tinto.) Stage 2: Froth flotation
Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper. A continuous process called floatation, which uses water, various flotation chemicals, and compressed air, separates the ore into fractions.
