how mercury is made material, history, used, processingthe most common ore is red mercury sulfide (hgs), also known as cinnabar. the presence of g, silver, and base metals is detected using various chemicaltesting methods. mining and processing mercury ore can expose workers to mercury vapor as well as to direct contact with the skin. the production of chlorine and caustic soda can alsohow copper is made material, used, processing, stepsthe development of more efficient processing techniques in the late00s allowed the mining of lowergrade copper ores from huge openpit mines in the western united states. cu 2 s, is another sulfide ore. cuprite, or red copper ore, cu 2 o, is an oxide ore. malachite, or green copper ore, cu g, silver, and other precious metals arephotos of g ores, quartz, telluride g ore and gnormally even good, rich g ore has no g metal which is visible to the naked eye. the photo at left shows small particles of metallic g in quartz taken from the mountains of canada. sections of gray colored quartz in the specimen have this appearance because of the finely disbursed sulfide crystals present in this ore.
indonesia Xinhaimcmoranthrough its subsidiary, ptfi, fcx mines one of the worlds largest copper and g deposits in the grasberg minerals district in papua, indonesia. in addition to copper and g, ptfi produces silver. fcx has a 48.76 percent interest in ptfi and manages its mining operations. ptfis results are consolidated in fcxs financial statements.g processing mining and concentrating britannicag processing g processing mining and concentrating the nature of the ore deposit determines the mining and mineral processing techniques applied. oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. in this case they are merely shattered by explosives and then piled into heaps fornorth america Xinhaimcmoranmolybdenum concentrate, g and silver are also produced by certain of fcxs north america copper mines. fcxs lone star project located near its safford operation in arizona is substantially complete and on track to produce approximately 0 million pounds ofcopper ore types sulfides vs. oxides an investor'snov 09, · there are two main types of copper ore of interest copper oxide ores and copper sulfide ores. both ore types can be economically mined, but they are processed in different ways.
copper mineral uses and properties geologynative copper was probably one of the early metals worked by ancient people. nuggets of the metal could be found in streams in a few areas, and its properties allowed it to be easily worked without a required processing step. copper's metallic luster attracted people's attention. today most copper is produced from sulfide ores.extractive metallurgy extractive metallurgy is a branch of metallurgical engineering wherein process and methods of extraction of metals from their natural mineral deposits are studied. the field is a materials science, covering all aspects of the types of ore, washing, concentration, separation, chemical processes and extraction of pure metal and their alloying to suit various applications, sometimes for directroasting (metallurgy) roasting is a process of heating a 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 component(s). often before roasting, the ore has already been partially purified, e.g. by froth flotation.
