Advantages of extraction of copper directly from sulphide ore is less favourable

important questions for cbse class 12 chemistry(iii) extraction of copper directly from sulphide ores is less favourable than that from its oxide ore through reduction. answer: (i) it is done so as to reduce its melting point and increase electrical conductivity. (ii) it is because cr is stronger reducing agent than zn. copper mining and extraction: sulfide orpper mining and extraction: sulfide ores. its hard to imagine a world without copper. we rely on copper for power, lighting, heating, communications, water supply and transport. copper makes our homes, schools and businesses efficient, comfortable and decorative and it lasts for many years. in this e-source, extraction of copper directly from sulphide ore is less extraction of copper directly from sulphide ore is less favourable than from its oxide ore through reduction.give reason. copper ore types: sulfides vs. oxides investing news networkcopper ore types: sulfides vs. oxides. copper sulfide ores are typically the most profitable types of copper ores to mine. that is because they have high copper content, and the copper in them copper(ii) extraction from ammonia leach solutiontype of diluent and is less favourable for systems with non-aliphatic diluents. it was observed that ammonia co-extraction occurs and depends on examined parameters. scrubbing of loaded organic phase showed that ammonia can be removed almost completely using double wash with sulfuric acid solution. copper ore hydrometallurgy and pressure leaching-copper-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. hydrometallurgy is advantageous in flexible capacity, minimized investment and less complicated equipment, functioning as an effective supplementary to copper pyrometallurgy. the method of processing bismuth sulfide ores and the method of processing of sulfide ores is trichosis fact, the translation of bismuth in the solution in the leaching is carried out by treatment of the ore or concentrate with sulfuric acid for a predetermined period of time while applying heat and ph less than 2 and then the rest from the leaching residue, enriched with precious metals and depleted bismuth, is separated from the leach solution. copper ore types: sulfides vs. oxides investing news networktypes of copper ore: oxides. as mentioned, copper oxide ores are not as attractive an exploration target as copper sulfide ores due to their lower grade. however, in some cases low-grade copper extraction of copper directly from sulphide ore is less click here 👆 to get an answer to your question ️ extraction of copper directly from sulphide ore is less favorable than from its oxide through reduction. extraction of copper directly from sulphide ore is less extraction of copper directly from sulphide ore is less favourable than from its oxide through reduction. explain.

(ii) it is because cr is stronger reducing agent than zn. the bioleaching of sulphide minerals with emphasis on copper the bioleaching of sulphide minerals occurs in an acidic medium that often contains a considerable concentration of iron(iii). while the emphasis here is on bioleaching, acid leaching and galvanic interactions between sulphide minerals and iron(iii) also contribute to the overall efficiency of the leach. pyrometallurgy for extraction of copper from sulphidecopper 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 why is the extraction of copper from pyrites more difficult therefore, h2 and c cannot reduce cu2s to cu. on the other hand, the gibbs free energy of formation of cu2o is greater than that of co. hence, c can reduce cu2o to cu. c(s) +cu2o(s) 2cu(s) + co(g) hence, the extraction of copper from its pyrite ore is difficult than from its oxide ore through reduction. in the extraction of copper from its sulphide ore, the metal extraction of copper directly from sulphide ore is less favourable than from its oxide through reduction. explain. asked dec 18, 2017 in chemistry by sforrest072 ( 127k points) extraction of copper directly from sulphide ore is less metal sulphides are generally difficult to reduce by carbon as compared to metal oxides. therefore, extraction of copper directly from sulphide ore is less favourable than from its oxide through reduction an hence, metal sulphides are converted to metal oxides which can be easily reduced to give us the metal ore.
