Figure shows the difference in energy efficiency between a laboratory ball mill and a stirred mill grinding a gold ore using 6 mm diameter alumina balls as media. At a fine grind size there is a clear advantage in energy consumption for a stirred mill over the tumbling mill. However, as the grind size coarsens, the difference in specific energy required to achieve the grind lessens.
technologies for oxide and sulphide ores versus ore grade is given in Figure 2. Figure 2 – Applicable Ore Beneficiation Technologies as a Function of Ore Grade for Oxide and Sulphide Ores. (Modified from Robertson et al., 2005) A chart showing identified applicable process categories for gold ore recovery is given Figure 3 (McNab, B., 2006).
Difference between oxide and sulphide ore mining process. Characterizing gold in refractory sulfide gold ore Gold is present in refractory sulfide gold ores mainly in arsenian pyrite and arsenopyrite where it occurs in both the chemically bonded state and as nanosize grains of metallic gold During roasting or pressure oxidation the
Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important byproduct of this process is used for the extraction of oxide ores. Pyroprocessing Sulfide Ores Provides Acid for Leaching
Differences In Processing Sulfide And Oxide Gold Ores. Iron oxide copper gold ore deposits these ore bodies range from around 10 million tonnes of contained ore to 4000 million tonnes or more and have a grade of between 02 and 5 copper with gold contents ranging from 01 to 3 grams per tonne parts per million,Differences in processing sulfide and oxide gold ores.
sulfide or laterite (oxide) resources. Historically production has been dominated by sulfide ores but future production is increasing shifting to laterite ores. The principal reason for this historically is that sulfide ores are easier to process, through conventional mining, smelting and refining, compared to laterite ores which
Copper Ore Types: Sulfides vs. Oxides. ... copper oxide ores and copper sulfide ores. ... Different methods are used to process copper sulfide ores depending on the concentration of copper within ...
Jul 09, 2019· 1 Types of copper sulfide ore (1) Single copper mineral Its ore characteristic is relatively simple, and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz, carbonate and silicate. (2) Coppersulfur ore Called copperbearing pyrite. In addition to copper minerals, iron sulfide can be recovered, and the main mineral of sulfur is pyrite.
Apr 23, 2011· Copper oxide ores. Copper oxide ores are not as attractive of an exploration target as the copper sulfide ore types due to their lower grade, however lowgrade copper oxide .

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of % pure copper called cathodes, which will ultimately be made into products for everyday most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, due to the different ...
Sulphide Gold Recovery. Preconcentration of coarse 350 – 500 micron sulphideassociated gold ore, using the InLine Pressure Jig, is required to reject gangue from the high value IPJ, a classic preconcentration device, is effective in gangue rejection prior to further processing of valuable goldbearing material.. Other turnkey modular systems for preconcentrating coarse ...
These studies were designed to determine the influence of various chemical and physical parameters on heap leaching and to establish a correlation between laboratory and field testing. Ores used in this Study. Several different types of oxide and sulfide copper ores were tested in this study. Table 1 gives a description of these samples.

In ore deposit geology, supergene processes or enrichment are those that occur relatively near the surface as opposed to deep hypogene processes. Supergene processes include the predominance of meteoric water circulation with concomitant oxidation and chemical descending meteoric waters oxidize the primary sulfide ore minerals and redistribute the metallic ore elements.
