· Extraction of cobalt from complex ore flotation concentrates obtained from the Blackbird Mine. Idaho. USA is reviewed. After flotation of a primary copper concentrate, a bulk concentrate is recovered containing major amounts of cobalt, arsenic, and iron, with minor amounts of copper and nickel. This concentrate can be upgraded during flotation
Pyrometallurgy usually adopts original ore, in which its content can reach 20%-30% after mineral processing. Copper concentrate is put into an airtight blast furnace, reverberatory, electric furnace, or flash furnace for matte smelting. The output of molten matte is then put into the converter for converting into a blister copper, and next into another kind of reverberatory.
· Effective costs of Copper Processing As each tonne of ore produces t of copper in concentrates, with a free market value of £, so total production costs of copper in concentrates : However, if the ore contains appreciable by-products, the effective production costs are reduced. Assuming the concentrate contains 25 gpt of gold and 70 gpt of silver,
process consists of matte making from copper ores, converting process to produce blister copper from matte, and the process to produce anodes to be used for electrolytic refining after reducing sulfur and oxygen in blister copper. The advantages of this process, the recovery rate of copper and precious metals is high. More than % purity electrolytic copper (cathode)
· With the gradual decrease in the grade of copper ores being processed, copper concentrates have become more complex with higher impurity and gangue content. This trend has had a detrimental effect on smelters as they have to increase throughput to maintain copper metal production, while increasing operating costs due to processing the increased amounts
· To extract the copper from the concentrate, a flash smelting process is used. Concentrate is sprayed into a reaction column in a flash furnace along with heated, oxygen-enriched air. The sulfide

While the use of this process is restricted by the strict growth environment such as temperature, pH, oxygen concentrate and light condition of microorganism and the long leaching period. How- ever, hydrometallurgical process does not have the problems mentioned before. Therefore, hydrometallurgical *Corresponding author. Y.

Key words: copper, roasting,oksidation,fluidized bed,mechanism 1. INTRODUCTION In copper production, starting raw materials are sulphide ores and copper concentrates. One of the most significant processes in the treatment of starting raw material is roasting in fluidized layer, since its success affects the succeeding calcine roasting phase
· The fluids appear to be the most primitive and copper-rich ore fluids identified to date . The entire assemblage of immiscible fluids—silicate melt, hydrothermal liquid, and hydrothermal vapor—provides a snapshot of a highly productive magmatic-hydrothermal transition. Perhaps more importantly, the assemblage highlights a geological process that
Find out how copper ore is extracted and turned into copper metal. This is a PowerPoint presentation showing the properties, uses and extraction of copper. It includes details of the mining and processing of copper ore as well as smelting, converting and refining to produce copper metal. Most slides contain photographs or labelled diagrams. Teacher's 
Typically, a zinc concentrate contains about 55% of zinc with some copper, lead and iron. Zinc concentration is usually done at the mine site to keep transport costs to smelters as low as possible. Zinc smelting. Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc.
The need for analysing copper concentrates to determine the copper content accurately and rapidly is increasing. Hence, there exists a demand for automated systems that perform the wet chemistry methods for the analysis of copper concentration in powder samples. Automation brings the advantage of increased hands-off capacity and improving accuracy and precision
Copper Concentrate Process. A schematic diagram of the conventional process for the production of copper and the SXEW process can be seen here Conventional Copper Extraction Conventionally copper is recovered by a pyrometallurgical process known as smelting In this process copper ore is mined crushed ground concentrated smelted and refined.

Copper Ore /copper concentrate /Raw Copper Ore/Copper Ore Lumps Currently, the most common source of copper ore is the mineral chalcopyrite (CuFeS2), which accounts for about 50% of copper production. The focus of this article is on the process of copper extraction from chalcopyrite ore into pure metal. Processes for other minerals are mentioned. Owing to our
Through earliest experimental study to tailings of Yangla copper ore known that under the best conditions of the flotation process can be obtained a copper concentrate which copper grade of % and recovery was %. Due to copper minerals embedded in this materials at a very fine particle size, and closely symbiosis with iron content and quartz, lead to it difficult to
In the second step of the production process, we concentrate the ore, which separates valuable minerals from the ore into a concentrated liquid. We turn the crushed ore into a slurry and transport it to flotation cells. We then mix the slurry with reagents to produce a bubbly froth. As a result, ore particles containing most of the valuable minerals adhere to the bubbles, which
Hydrometallurgical copper extraction process A process for the extraction of copper from a sulphide copper ore or concentrate comprises the steps of subjecting the ore or concentrate to agitation leaching at an elevated temperature and pressure to obtain a resulting acidic leach liquor containing dissolved copper and reducing the acidity of the resulting acidic
· A typical process might begin with grinding of the ore into a powder. This powder is processed with chemicals and air to separate out some of the unwanted material and concentrate the copper. Unwanted material from this step is referred to as the tailings. The tailings are typically disposed of in a tailings pond. Concentrated material from this step is then
Processing. Ore is mined and processed at an onsite flotation processing plant capable of treating up to 24 million tonnes per annum (Mtpa). The plant currently recovers copper, gold and silver into a saleable concentrate. The primary ore is crushed and ground using Semi-Autogenous Grinding and Ball mills to a final grain size of approximately
process is usually able to recover 85 to 95 percent of the copper in the ore. The dried concentrate contains approximately 20 -30 percent copper by mass, 30 per cent iron, 30 per cent sulphur, with the remainder including small amounts of gold, silver, and unwanted elements such as arsenic and mercury. Exported copper concentrates are transported by sea as a
· Chalcopyrite, being a primary sulphide, is the most common copper bearing mineral found in sulphide ores, containing up to % of copper. Given that many large open pit operations are aging, the pits become deeper and scarcer in secondary sulphides – at the same time being subjected to other complexities that can impact final copper recoveries and
ore is concentrated into high grade copper concentrates. The process of conversion, in copper or any mineral concentration process is known as beneficiation, because it involves the aggregation of low concentrated valuable minerals between % and 5% into high grade between 15 and 50 % that can be .
