The hulunbuir mountain gold mining co., Inner Mongolia Pick to: sanhe lead-zinc mining area is located in the root river city have to ear Boolean town 18 km south west, Boolean forest farm in the north west 9 km, administrative divisions under the root river city ear Boolean town jurisdiction. Mining area is located in erguna caledonian fold system - erguna caledonian fold belt, five card anticlinorium, has called the interruption in the south west, deposit consists of 17 with a total of 69 orebody, ore elevation of 1076.00 270.00 m, ore, quartz porphyry rocks as the Angle of andesite, andesitic volcanic clastic rock, the genesis of ore deposit types for low temperature liquid fissure filling vein lead-zinc (silver) ore deposit; Through laboratory process test, performance sulfide ore processing technology easy ore, zinc ore belongs to the lead and zinc oxide ore is optional; Medium deposit hydrogeological condition, engineering geological condition is simple, environmental geological conditions of medium. Based on the region and mining area formation, structure, surrounding rock and ore quality and ore deposit origin, ore-controlling factors, metallogenic model and prospecting marks sc will lead and
