Copper Recovery. Some copper ores are processes with heap leaching. Sulfuric acid is used to dissolve copper carbonate ores. The general reaction is. Cu2CO3(OH)2 (s) + 2H2SO4 ® 2CuSO4 + H2CO3 (aq) + 2H2O. Copper sulfate is soluble in water, so can be readily processed. The carbonic acid (H2CO3) will probably break down to carbonate and water ...
COPPER Copper production
Sulfide ores are used to produce a matte (40 – 50 wt % Cu) and a disposal slag (ca. wt % Cu). In contrast, oxide ores are processed directly to impure black copper ( 95 wt % Cu) and to a copperrich slag. The two ore types can be smelted together to produce matte and a slag with low copper .
How Gold Is Mined | Gold Mining Process | World Gold Council
Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well as how to extract and process the ore efficiently, safely and responsibly. On average, it takes between 1020 years before a gold mine is ...
Introduction to Mineral Processing
Autogenous (AG) and SemiAutogenous (SAG) milling has seen increased use in recent years, especially in large mineral processing operations. These mills typically have a large diameter relative to their length, typically in the ratio or 2 or to 1. AG mills employ ore as the grinding media. However, one the challenges with AG mills is that ...
An Introduction to the Electrolysis Process
In this process, the blister copper is cast into large slabs which are used as anodes in the electrolysis apparatus. The anodes are immersed in an electrolyte containing copper sulfate and sulfuric acid. Pure copper hodes are arranged between the anodes, and a current of more than 200A is passed through the solution. This causes copper atoms to dissolve from the impure anodes and form ...

Iron Mining Process
Iron Mining Process. From blasting to crushing to separation – more than 85% of the iron mined in the United States is mined in northeastern Minnesota to make our nation's steel. Blasting Taconite is a very hard rock. Using explosives, the taconite is blasted into small pieces. Transportation The taconite pieces are scooped up by electric shovels. Each shovel can hold up to 85 tons of rock ...
Understanding water use in mining and mineral processing ...
It is used in various steps in the process to recover valuable metals from ore. The water use is quite high – for example, around 1600 litres of water are used to obtain the 19 kilograms of copper found in a mediumsized family car. Water is not always readily available for processing operations. In many loions where mining operations occur, such as in remote Australia, water is a scarce ...

Crusher For Copper Ores
· Copper mining and processing processing of copper processing is a complied process that begins with mining of the ore less than 1 copper and ends with sheets of pure copper called hodes, which will ultimately be made into products for everyday most common types of ore, copper oxide and copper sulfide, undergo two different processes, .
Copper Ore
In most cases, the thinlayer process was used where crushed ores (80% − in) were stacked in heaps of 3–8 m height after agglomeration and sprayed at flow rates of 6–40 L·hour −1 ·m −2 with 15–90 days duration for copper oxides and 10–18 months for sulfides. Of note, 80%–85% copper extraction was commonly achieved.
PHASES OF A MINING PROJECT
Placer mining Placer mining is used when the metal of interest is associated with sediment in a stream bed or floodplain. Bulldozers, dredges, or hydraulic jets of water (a process called 'hydraulic mining') are used to extract the ore. Placer mining is usually aimed at removing gold from stream sediments and floodplains. Because placer

From Ore to Finished Product
Copper From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (coppertin alloy) about 3000 BC, was the first engineering material known to man.
Rod mills, how they function
Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at to Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of ...
