Oxide ores are generally processed using hydrometallurgy. This process uses aqueous (water-based) solutions to extract and purify copper from copper oxide ores at ordinary temperatures, usually in three steps: heap leaching, solvent extraction, and electrowinning. Heap Leachingis the process of using percolating …

As an example of a convention al thickener, Taggart (1945) records the Mt Lyell copper concentrate thickener as being 6 metres diameter by 3 metres high, and pro cessing 150 ton per day to give a ...

Abstract and Figures. Aqueous slurries' dewatering using gravity-driven thickeners is an essential unit operation in mineral processing. Thickener feed dilution is often used for enhanced ...

Problem: The feed to a flotation plant assays 0.8% copper. The concentrate produced assays 25% Cu, and the tailings 0.15% Cu. Calculate the following: (88) ...

for: rougher concentrate regrinding testing, copper concentrate, thickening and filtrationrheology testing, and final tailings rheology and thickening testing. No further confirmatory testwork was undertaken during the feasibility study optimisation review or FEED phase. Table 2.

The project mainly includes six sub-projects, namely the concentrate filter press workshop, the copper concentrate thickening ponds, the sulfur concentrate thickening ponds and conveying pump room, the tailings thickening ponds and conveying pump room, the processing plant collection ponds, and the tailings chutes.

A high-rate thickener dewaters the bulk of copper-moly concentrate before more separation. 5. Moly Flotation. The moly flotation circuit has similar groups of flotation cells with chemicals to float the molybdenite (moly concentrate), and settle out the copper sulfides (copper concentrate). 6. Copper Thickening/Dewatering

thickening stage. Ignoring these aspects leads to various operational problems in industrial tailings and copper-concentrate thickeners such as not achieving overflow quality or the percentage of solids required in the underflow. In recent years CI-JRI has designed and built two pilot columns, 1 and 4 meters

The conventional treatment of copper–gold concentrates involves smelting, converting, and electro-refining to produce a copper-cathode product. ... The flowsheet …

The operation of dewatering is performed in two stages. First, the bulk of the water is removed in a thickener, from which the concentrate is discharged as a thick pulp ; as a rule the underflow …

The dewatering of tailings is one of the serious challenges that the mining and mineral processing industries have encountered internationally. Solid–liquid separation methods are applied to wastewater, which generally consists of fine particles and water; fine particles are settled in thickeners by the flocculation method and the cleaned water is …

This paper presents residence time distribution (RTD) functions acquired in radioisotope tracer experiments carried out on a copper ore thickening, filtration and drying system. The radioactive isotope 64 Cu was selected as a tracer for copper. It was obtained through the activation of the natural ore concentrate in a nuclear reactor.

To make the separation of the valuable ores like copper concentrate, zinc concentrate, iron ore concentrate, lead concentrate, gold concentrate etc.. from the tailings, is used one of the following processes: ... The slurry of concentrate ores goes through thickening and then filtering and dewatering process before finally landing at the ...

The flowsheet (see Fig. 7) comprised fine grinding of the concentrate, pressure leaching, thickening and filtration, copper SX/EW, with a bleed circuit to recover valuable base metal co-products. Gold and silver were recovered from the autoclave residue by direct cyanidation.

The process plant design for the project is based on a metallurgical flowsheet designed to produce copper concentrate with a nominal throughput of 6,600 tonnes per day ("tpd") with a planned availability of 92% for the first three years and 6,800 tpd with an availability of 95% in the subsequent years. ... concentrate thickening, filtration ...

COPPER THICKENING AND FILTERING. The thickening and filtering is similar to other milling operations, however, as the porphyry copper installations are often in arid areas, the mill tailing is usually sent to a large thickener for water reclamation and solids go to the tailings dam. ... The concentrate can then be reground and refloated …

Thickening is a process where a slurry or solid-liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water (or liquor in leaching processes). The driving force for the separation is gravitational, where the differences in phase densities drive the separation of the solids and liquid.

The last step of the process before the copper concentrate filtration is the thickening of the copper concentrate slurry by the high rate thickener. Case Study on Copper Concentrate Filtration.
