in deposits mined today zinc ore rock containing economic content of zinc and/or other materials commonly also contains lead silver and in some cases copper and the zinc is extracted as a coproduct along with these other metals.the discovery of a large zincleadsilver orebody at broken hill in 1883 a mine is still in operation today
zinc is the 23 rd most abundant element in the earth's crust. sphalerite zinc sulfide is and has been the principal ore mineral in the world. zinc is necessary to modern living and in tonnage produced stands fourth among all metals in world productionbeing exceeded only by iron aluminum and copper.
mining industry requires high amounts of energy to extract and process resources including a variety of concentration and refining processes. using energy consumption information different sustainability issues can be addressed such as the relationship with ore grade over the years energy variations in electricity or fossil fuel use. a rigorous analysis and understanding of the energy
the value per ton of crude ore is then $10 for lead concentrate and $8.50 for zinc or a total of $18.50 per ton of crude ore. by perfect concentration assuming the lead to be as galena and the zinc
the most common zinc ore is sphalerite more commonly referred to as blende. it is a zinc sulphide zns. in its mineral form zinc is often used with lead but can also be used with copper gold and silver. zinc mining resources are widespread throughout the world. zinc ore is present in over 50 countries.

the invention discloses a manufacturing method of metal lead and zinc through waste slag with lead and zinc or lowgrade lead or zinc oxide which comprises the following steps: grinding lead zinc slag or lead zinc oxide into 0.11mm; stirring and leaching through strong base solution under 10100 deg.c for 301000min; filtering; draining filtrate; electrolyzing filtrate directly to generate lead with current density at
noticeably the zinc recovered from silverzinc crust can be used as desilvering agent again for the parkes process. while the lead alloy can be charged to lead refining pot before bismuthremoving step. this system is superior in reducing energy consumption shortening process flow and improving working environment.
lead & zinc 10 lead & zinc l ead is a soft heavy toxic and highly malleable metal. it is bluish white when freshly cut but tarnishes to dull grey when exposed. both lead & zinc are found to occur together in ore along with other metals such as silver & cadmium. zinc is a silvery bluegrey metal with a relatively low melting and boiling point.
in terms of zinc pyrometallurgy horizontal and vertical retorting has been abandoned due to its high energy consumption low recovery rate and environment pollution. the other three process used in existing smelters accounts for only about 15% of global zinc production.
