Development of a sequential extraction procedure for iron

Jan 25, 2005 Table 1 details the concentrations of iron removed by the different extraction techniques for a range of Fe minerals. The data shown relate to the optimum extraction times determined for each technique. Tests of the effectiveness of various acetate extractions for the dissolution of crystalline siderite were complicated by the fact that natural siderite rarely occurs in pure form.

Extraction of Iron, Iron Mining, Iron Ore Processing

For the extraction of iron from siderite with fine grain size, effective extraction of iron include roasting magnetic separation, strong magnetic separation, flotation or magnetic flotation combined process. Siderite containing magnetite can be separated by a combined iron ore processing method of weak magnetic separation and gravity separation

Determination of chemical composition of siderite in

Jan 15, 2009 The influence of time extraction from 0.5 to 8 h for HAc of concentrations of 0.1 and 0.25 mol L −1 on iron concentration was rather insignificant. The mean iron concentration equaled 0.67 ± 0.03% (m/m) for these extraction conditions. This quantity of iron resulted from the presence of this element in dissolved calcite.

What is the magnetite hematite (siderite) separation

According to the types of iron-containing content, the common iron ore can be divided into magnetite, hematite, martite, v vanadium titano-magnetite, limonite and siderite ore and mixed iron ore that consists of two or more than two iron-containin...

How to Remove Arsenic, Antimony & Bismuth from Copper

Feb 06, 2017 The ores of copper are usually associated with minerals containing arsenic, antimony and bismuth.Whatever the means adopted for extracting the copper, these metals are usually found, to a greater or less extent, in the product. There is, however, usually some elimination in the various metallurgical operations to which the ores are subjected, and some attempt is made here to

Why was arsenic added in the extraction of copper? Quora

The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite (CuFeS2[math]CuFeS2[/math]) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (a...

The separation of arsenic from copper in a Northparkes

Oct 19, 2007 In order for the high-arsenic regions of the Northparkes copper–gold orebody to be beneficiated economically, tennantite ((Cu,Fe) 12 As 4 S 13) present in the ore needs to be rejected to enable copper concentrates to meet the typical smelter penalty level of 2000 ppm As. Using a composite sample of high-arsenic drill cores from Northparkes it was possible to selectively separate tennantite

Extraction of arsenic Hydrometallurgy: Leaching in Heap

TBP has been reported as used for extracting arsenic from copper sulphate solutions and it was tested also at some copper refineries in Chile in the early 80´s. However the big mystery was how organic reagent affected the normal smoothing agents in copper ER. Extractions were good but built up was not possible to measure in such a short time.

Sep 01, 2009 Copper ores and concentrate samples used in this work have been obtained from different sources or locations with differing amounts of copper and arsenic ranging from 10 to 40 wt.% and 0.8 to 14 wt.% for the two elements respectively, containing mainly enargite as the main carrier of arsenic in its structure.
