Specifically, for the copper production partitioning of 210 Pb and 210 Po from uranium occurs into the copper concentrate during the smelting process. These radionuclides are vaporized at the smelting stage and may accumulate in dusts collected from off gases.
The copper ore usually contains a large amount of dirt, clay, and a variety of non-copper bearing minerals. The first step is to remove some of this waste material. This process is called concentrating and is usually done by the flotation method. 3 The ore is crushed in a series of cone crushers.
The copper concentrate processing equipment needed in copper ore processing is complex because of the different property of copper concentrate. However, the main copper processing equipment for copper ore is same as other mining processing steps, including crushing, grinding, flotation separating and …

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: smelting and classification; The smelting of copper; Copper that is mined from copper ore, after beneficiation, becomes high quality copper concentrate. Then, after being smelted, refined copper and copper products are yielded. There are two ways of smelting copper, one is pyrometallurgy, the other hydrometallurgical.

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.
Toowong Process–The Toowong Process is being developed by Core Resources, Brisbane, Australia. It is a patented alkaline leach process for the removal of arsenic, antimony and other penalty elements from copper, lead and nickel sulphide concentrates, and antimony from gold concentrates.
The Verti-Press filter is used at the end of the concentrator cycle to filter and dewater the copper slurry prior to the drying cycle and the smelting process. Prior to the Verti-Press Filter technology, Falconbridge used rotary vacuum drum and thermal dryers to filter, dewater and dry the copper concentrate slurry.
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 (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
for its minerals. It is important to note that our gold/copper/silver concentrates are already a highly processed and beneficiated product. Whilst the smelters do charge to process our concentrate, on average for the contract terms that we have agreed with the overseas smelters, we receive 97% of the total value of gold, silver and copper.
The way most of the majors handle it is to smelt the copper concentrate and then do a sx/ex process to refine the copper and then cyanide the sx/ew sludge. Again simple, but not easy. The simple and easy way is not to worry about it. ... BUY Laboratory & Small Plant Process Equipment
