metal extraction from sulfide ores

Metals are often found as compounds in ores An ore is a rock or mineral that has enough metal in it to make it worth extracting Mining copper About 200 years ago the UK was an important world source of copper and tin and there were mines in Cornwall and Devon

Metal extraction from ores occurs in many different ways involving physical, chemical and electrical means Even ores of the same metal sometimes require different methods of separation depending on the concentration of the metal and its chemical composition within the ore Ores are naturally occurring sources of metal

How to Extract Precious Metals From Sulfides Extract sulfide ore deposits from the ground and place in to the crusher to mince ore from 5 to 50 micrometers Crushing begins the separation process by preparing the ore to be floated in water First, the ore is crushed using a gyratory crusher to reduce the ore to 6 inch diameter pieces

Extraction of zinc, the principal valuable component of the complex sulfide ores, with the simultaneous separation of lead sulfate during direct ore processing and possible accumulation of precious metals dispersed in sulfide matrix, will be probably advantageous if technical problems were resolved

Copper hydrometallurgy is a branch of metallurgy method to extract copper directly from those difficult to concentrate copper oxide ore Traditional copper hydrometallurgy process typically consists of atmospheric leaching, solvent extraction SX and electro winning EW It can produce either copper cathode or copper sulphate crystal

Isolation of elements in Chemistry class 12 aims to teach the students about various processes of extraction of metals from ores Very few metals such as the noble metals, i e , Gold, Silver, and Platinum etc are present in their original metallic forms in nature

A metal ore is a mixture of minerals containing the metal, and other materials in the rock, from which it is economically viable to extract the metal A high grade ore produces a high yield of metal A low grade order produces a low yield of metal Most metal ores occur as a metal oxide, a metal sulfide or a metal

Weathering of sulfide ore bodies Ore blasting Fig 1 Blasting sulfide ore in the Codelco Chuquicamata open cut copper mine, Chile The first step in recovering metals from their minerals is that of finding ore bodies in which metal sulfides are present in a sufficient quantity, and at a sufficient concentration, for mining to be economic

Several sulfide ore leaching methods were tested to determine the best base metal extraction technique as a first step in designing a process to recover the base and precious metal values Leaching reagents used included dilute sulfuric acid, sulfuric acid plus manganese dioxide, ferric chloride plus hydrochloric acid, and oxygen

Apr 24, 2010 Most sulfide deposits have traditionally been processed by concentration through a froth flotation process followed by pyrometallurgical extraction Nickel is extracted from its ores by conventional roasting and reduction processes which yield a metal of greater than 75 purity

The Cuprex metal extraction process produces cathode grade copper using a hydrometallurgical process based on chloride leaching of sulfide ore concentrates

Sulfide ores are not reduced directly to the metal but are roasted in air to convert them to oxides Gangue or Matrix The gangue or matrix is an unwanted, commercially useless, rocky, earthy or sandy materials that are found with the ores These are the impurities are filtered out at a later stage Extraction of Metals

Additionally, for gold and copper extractions, bioleaching is used to extract cobalt, zinc, nickel, and uranium from low grade ores and industrial effluents In this review, the fundamental process of bioleaching from low grade metal sulfide ores are discussed with emphasis on mechanism, types, pathways, techniques, and bioleaching development

Jetti Resources is a technology driven natural resources company that has developed a novel hydrometallurgical technology to extract metals of value from mineral ores that the mining industry has struggled to process

Roasting is a process of heating of sulfide ore to a high temperature in presence of air It is a step of the processing of certain ores More specifically, roasting is a metallurgical process involving gassolid reactions at elevated temperatures with the goal of purifying the metal components Often before roasting, the ore has already been partially purified, e g by froth flotation

An ore is any naturally occurring source of a metal that you can economically extract the metal from Aluminum, for example, is the most common metal in the Earth's crust, occurring in all sorts of minerals However, it isn't economically worthwhile to extract it from most of these minerals

Extracting of Copper from Other Ores Copper can be extracted from non sulfide ores by a different process involving three separate stages: Reaction of the ore over quite a long time and on a huge scale with a dilute acid such as dilute sulfuric acid to produce a very dilute copperII sulfate solution

Several sulfide ore leaching methods were tested to determine the best base metal extraction technique as a first step in designing a process to recover the base and precious metal values Leaching reagents used included dilute sulfuric acid, sulfuric acid plus manganese dioxide, ferric chloride plus hydrochloric acid, and oxygen

As with oxide ores, solvent extraction and electrowinning technologies are used to recover the copper from the pregnant leach solution Supergene sulfide ores rich in native copper minerals are refractory to treatment with sulfuric acid leaching on all practicable time scales, and the dense metal particles do not react with froth flotation media

Sulfide Ores Sulphide ores were mostly created by i the intrusion of molten magma from the mantle into the crust of the earth and ii the formation of localized metal rich sulphide ore bodies by sequential solidification and/or hydrothermal leaching and precipitation
