When copper concentrate is smelted the rhenium volatilizes in the flash smelting process off-gas process and is recovered in the Acid Plant Blow-down (APB). APB is treated in the Hydromet Plant along with refinery bleed solutions to recover copper while fixing bismuth and other impurities in a form suitable for discharge to tailings. Rhenium is recirculated to the smelter and can build to high ...
The flash smelting process is an example of an energy-saving pyrometallurgical process in which iron and sulphur of the ore concentrate are oxidized. The exothermic reaction coupled with a heat recovery system saves a lot of energy for smelting. The high sulphur recovery of the process is also beneficial for environmental protection. Most of the recently built copper and nickel smelters use ...
The current major tin smelting process diagram production comes from placer or alluvial deposits in Malaysia, Thailand, Indonesia, Maakhir region of Somalia, and Russia. Hydraulic mining methods are used to concentrate the fine particles of ore owing to its high specific gravity of about 7.0 G.
The smelting process typically produces less than 3 tons of solid waste per ton of copper produced. Pollution Prevention and Control. Process gas streams containing sulfur dioxide are processed to produce sulfuric acid, liquid sulfur dioxide, or sulfur. The smelting furnace will gen-erate process gas streams with SO. 2. concentrations ranging from 0.5% to 80%, depending on the pro-cess used ...
In the smelting process, either hot calcine from the roaster or raw unroasted concentrate is melted with siliceous flux in a smelting furnace to produce copper matte. The required heat comes

In flash smelting, the concentrate is dispersed in an air or oxygen stream and the smelting reactions are largely completed while the mineral particles are still in flight. The reacted particles then settle in a bath at the bottom of the furnace, where they behave as does calcine in a reverberatory furnace. [31]
The Oxygen Flash Furnace At the Asarco copper smelter in Hayden, Arizona, the oxygen flash furnace is initially heated up with natural gas. It becomes so hot that the copper concentrate immediately ignites when it is blown into the furnace along with oxygen and a silica-bearing flux.

This process developed by the Imperial Smelting Corporation, Ltd., is progressively being expanded into the zinc smelting industry. It is a process for smelting sinter-roasted zinc concentrates with coke in a blast furnace. The blast furnace gasses typically contain 5-6% Zn and 8-10% CO2 are brought into contact with a shower of molten lead to condense the zinc vapor for recovery as metal. The ...
Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.
The lead reduction smelting process involves two-steps: a fusion of the ore material with lead in a carbon-rich environment, followed by the separation of silver from the lead in an oxygen-rich environment.
Gold processing plant solutions by APT incorporate the RG Scrubber wash plant with the world renown FL-Knelson concentrator or APT's GoldKacha for optimal gold recovery.
The production process consists of: Concentrate smelting to obtain copper blister with 99% Cu content in a flash furnace during a three-phase cycle (pressing of the concentrate, smelting of the copper matte, and converting); Processing of blister copper in rotary and stationary furnaces to obtain anodes; Electrorefining of anodes to arrive at the final product - 99.99% pure cathode copper. The ...
MINING TO SMELTING - GOLD/COPPER CONCENTRATES IN DETAIL INTRODUCTION Rocks are mined and then trucked to the process plant Acacia operates three gold mines in Tanzania: Bulyanhulu Gold Mine, Buzwagi Gold Mine and North Mara Gold Mine.
This process is only one truly continuous process established in a commercial scale all over the world, which has a superior technology for copper smelting and converting. It is recognized as the most cost effective and environmental friendly process, and yielding anode copper directly from copper concentrate

The concentrate is fed to roasters where sulphur is removed as SO 2 gas and sent to the sulphuric acid plant for treatment. The roaster product (calcine) is fed to the electric furnace.The furnace produces a matte that contains desirable metals like nickel, copper and cobalt as well as a slag that is stockpiled on site and is managed to strict environmental standards. The furnace matte is then ...
