The Phu Kham Copper-Gold Project was the second development phase of the Phu Kham deposit and uses a conventional process technology followed by flotation to produce a copper-precious metal concentrate.
The new process offers an effective way to dissolve concentrate, remove impurities, and recover copper as LME A-grade cathodes. In addition, the flowsheet can be modified to recover silver and gold. It is an easy-to-operate, self-optimizing plant that provides high availability and fast ramp-up to production.
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 …

In mining, when flotation is finished with the ore, and a final concentrate has been produced, often, both products will go to a concentrate thickener before it is dried for shipping. This is a very important step so here we discuss Basic Concentrate Thickener Operation.
Copper industrial minerals include: natural copper, chalcopyrite, chalcocite, tetrahedrite, azurite, malachite, etc. Chalcopyrite (a compound of copper, sulfur, and iron) is mined mainly, followed by chalcocite and bornite. If copper ore wants to be fully utilized, it must be processed by flotation. Flotation separation is an important copper ore …
In the first case study, the P1 model was applied to an industrial plant to validate the methodology. The industrial plant was a copper concentrator plant located in northern Chile. The industrial plant consisted of a circuit for the recovery of water from flotation tails, which comprised a battery of 10 hydrocyclones that were connected in series and a …
In copper smelting, obtaining uniform blend compositions from diverse copper concentrates is vital for stable and economical operation, keeping in mind the decreasing quality of raw material with time. The concentrates differ in chemical compositions and contain around 24 critical elements, making it challenging to achieve …

producing an average of 160,000 tonnes of copper in concentrate per year. To optimize the operation, ramp up production and prevent damages to ... process control and advanced instrumentation suite of products, the ECS/ProcessExpert system and the Impactmeter. The ECS/ProcessExpert system is an advanced process control solution …
Conventional flotation plant optimization procedures for copper and copper–gold ores have served the industry well over decades. But with the present trend in declining ore grades along with increase in metallurgical complexity, many flotation operations are experiencing significant challenges in sustaining design or operational …
Copper concentrates are widely used in smelting operations worldwide and typically consist of chalcopyrite (CuFeS 2) as the primary mineral, with chalcocite (Cu 2 S) and bornite (Cu 5 FeS 4) as secondary copper-bearing minerals.However, these concentrates often contain hazardous impurities, such as the fluorine ion, which can …
plant into the main process flow sheet, some heavy liquid separation (HLS) test work was carried out on the –6 mm to +1 mm fraction of the reef material. Results showed that a DMS plant operating at a cut density of 2.7 t/m3 would theoretically reject 30 percent of the mass, lose 9% of the copper to waste at a grade of 0.4% copper.
Capricorn Copper Mine (CCM) is an underground copper mining operation located 125 km northwest of Mt Isa in North West Queensland, Australia. The plant restarted operations in late 2017 after being in care and maintenance for a number of years. After plant start-up in early 2018, copper recovery was well below the study expectation. Plant data confirms …
8 times more copper than petrol/diesel alternatives; renewables use around 5 times more copper than conventional power systems2. Factors such as these justify predictions of a copper supply shortfall of more than 15 million tonnes by 2034, based on current mine production3. …tightening supply Efforts to meet the increasing demand for copper
In this process, air is blown through the mixture, and the copper floats to the top. The copper is then removed with a skimmer. At …
Copper Concentrate Production Process. From its initial state as copper ore, the journey to becoming a high-quality concentrate suitable for diverse industrial uses is long and intricate. The process of turning this ore into a copper concentrate involves multiple steps, spanning from mining copper to chemical reactions, physical modifications ...
The Mount Isa Mines (MIM) copper concentrator at Mount Isa processes both chalcopyrite ore from the MIM underground mine and rotary holding furnace (RHF) slag from the MIM copper smelter. There have been numerous changes to the processing practices since commissioning this concentrator in 1973. Current management of the concentrator …
In the second step of the production process, we convert the ore from a low-grade material into a concentrate of high-grade copper inside the Concentrator Complex. The technique all begins with a wet grinding process that turns the crushed ore into a slurry and transports it to flotation cells. When mixed with water, reagents, and air, the ...
In some cases, the concentrate is submitted to an additional processing step to extract a by-product (e.g. molybdenum sulfide). Finally, the copper concentrate is dried ready for transportation to the next step (smelting). The copper concentrate production process does not involve any chemical modification of the original ore body. 2.
