The Yinshan deposit in the Jiangnan tectonic belt in South China consists of Pb Zn Ag and Cu Au ore bodies This deposit contains approximately 83 Mt of the Cu Au ores at % Cu and g/t Au
A Cu Pb Zn sulfide ore from Somincor Neves Corvo Portugal with a chemical composition of % Cu % Pb 7% Zn 32% Fe and 43% S was used The ore sample is a massive sulfide ore containing chalcopyrite galena sphalerite and pyrite as
Jinchanghe is a Zn Pb Fe Cu skarn deposit in the northern Baoshan block southwestern China It is a typical distal skarn deposit with orebodies in the Cambrian Hetaoping Formation limestone and calcareous siltstone The skarn minerals display a vertical zonation with garnet skarn in the lower part and pyroxene skarn in the upper part Economic metals are also

With the continuous development of science the application of metallic tin has gradually expanded resulting in a growing global demand for tin However with the reduction of easily selectable tin ore improving the level of separation of fine and micro fine tin ore resources is of great significance to the development of the tin mining industry
The responses of the lead zinc Pb Zn ore bearing veins in the Asu River Group shales in Abakaliki area to ground magnetic resistivity and induced polarization IP methods of geophysics were studied in Nkpuma Ekwoku Results of the study indicate that low magnetic susceptibility values are associated with shallow tectonic structures within the
This contribution presents the first multi scale geophysical investigation conducted in the Abakaliki and Obubra mining districts AOMD southeastern Nigeria for the exploration of shallowly emplaced < 50 m massive sulfide and barite mineral deposits Raw airborne magnetic data covering the AOMD was acquired and subjected to diverse
The results demonstrate that the ore consists of 35 categories of minerals assaying Cu % Pb % and Zn % in the forms of chalcopyrite galena and sphalerite respectively and silver
Therefore the grinding process of copper sulfide ore should be optimized according to the ore properties such as ore hardness mineral composition and liberation size In addition the grinding process of copper sulfide ore is affected by many factors such as the type of grinding media the grinding time the pH value of the slurry and the
Weilasituo ore field is located in the southern part of Great Xing an Range Inner Mongolia of northeastern China with two main ore deposits one is previously found Cu Zn deposit and another is
About Pb Cu Lead and zinc are extremely close in nature especially in primary deposits and often coexist Most of the lead zinc minerals are sulfides and sulfates and galena and sphalerite are the primary Pb Zn ores Non sulfide It is formed due to hypogene and supergene weathering Mostly oxide ores like zincite and cerussite may fall under this category
Request PDF The effect of water chemistry on froth stability and surface chemistry of the flotation of a Cu Zn sulfide ore Water shortages have a direct impact on the life of many mining and
a complex Cu Zn ore from the northwest of Turkey [25] The results of aging tests showed that the flotatio n performance copper recovery and Cu Zn selectivity was negatively affected after a two week stockpile period For this type of ore the mine schedule/ore production should be optimized to mini
Garnet is the most common alteration mineral in skarn type deposits and the geochronological research on it can limit the mineralization age The Longwan Pb Zn deposit situated within the Fozichong Pb Zn ore field in Guangxi lacks precise geochronological data limiting the in depth comprehension of its genesis and tectonic setting
In this paper effects of temperature sulphate SO 4 2− thiosulphate S 2 O 3 2− and calcium Ca 2 ions on the flotation performance of a Cu Pb Zn complex sulfide ore were investigated using a statistical experimental design and modelling approach The results were evaluated using ANOVA and regression analysis to determine the
tively 88% with grade of % in Cu concentrate and 81% with grade of % in Pb concentrate Keywords Optimization Differential flotation Copper sulfide oxide ore Ghozlo mine 1 Introduction Unlike lead zinc and copper zinc deposits that are abun dant in the world there are limited amounts of deposits that contain the compounds of all
Copper Cu is a significant metal for the society development and scientific progress and chalcopyrite is one of the main sources [1] Therefore the efficient separation and enrichment of chalcopyrite appear to be particularly important especially the flotation separation of chalcopyrite from sphalerite [2] The traditional chalcopyrite collectors such as xanthates dithiophosphates
Surface oxidation of the sulfide minerals negatively affects the flotation performance the selectivity and even the recoveries at heavy oxidation conditions Oxidation may take place during the formation of the ore during mining and stockpiling and during the flotation process Stockpiling of large amounts of ore is a common practice in mine sites for
The Tianbaoshan deposit is a typical large Pb Zn deposit in the SYG area and occurs as pipe like type hosted by Sinian dolostone It contains ∼26 Mt Zn Pb ore % Zn % Pb and g t −1 Ag and > Mt Cu ore % Cu In this study the detailed mineral textures mineral chemical and sulphur isotopic
The mining waste is deposited in several heaps and two sludge lagoons containing 380 000 m 3 of material As and Fe minerals predominantly arsenopyrite and pyrite were during the ore dressing process suppressed and moved to the waste The gangue minerals are represented mainly by carbonates and quartz The schist fragments occur only rarely
