CopperZinc ores Danafloat
CopperZinc ores. If the talc levels are sufficiently high and negatively impact metallurgy, talc depressants can be used in both the copper and zinc flotation circuits. These depressants include carboxymethyl, cellulose, dextrin, guar gum, and starch. Talc flotation interference can also be managed with proper frother selection.

Underground Mining. The length of the longwall block is about 3,000 meters to 5,000 meters. In a 3 meter thick coal seam the amount of coal in place in a block is six to seven million tons. The basic equipment is a shearer (a cutting machine) mounted on a steel conveyor that .
Copper Mining Extraction Process Flow Chart
Copper Mining Extraction Process Flow Chart. This solution is tapped off from the bottom of the pad and placed into big tanks with steel plates an electrical current is passed from the tank to the steel which is then electroplated with pure copper. This process as the advantage of avoiding the smelting and refining stages required for sulfide ores.

Primary Copper Smelting
Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 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.

6 Copper mining, Production Wastes and the Environment. Common ailments include respiratory illnesses such as asthma and tuberculosis as a result of inhalation of the silica dust particles resulting from the mining and processing of copper. Miners in particular suffer from silicosis or pneumoconiosis.
Copper Ore Processing Methods
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and directsmelting ores are produced, the bulk of the copper ore mined is concentrated.

Tailings produced from the milling of sulfide ores — primarily copper, lead, and zinc ores — may have concentrations of pyrite that are greater than those common in waste rock. Also, because tailings are composed of small mineral particles the size of fine sand and smaller, they can react with air and water more readily than waste rocks.

There are two distinct types of copper ore, the sulfide ore and the oxide ore. The sulfide ores are beneficiated in flotation cells, while the oxide ores are generally leached. First the copper ore from a open pit mine is blasted, loaded and transported to the primary crushers.
