Abstract: Aiming at full use of limited mineral resources, reasonable development of low grade and associated mineral resources, molybdenum tungsten concentrate market price was analyzed and forecasted, and two major influence factors of concentrate price and recovery rate were considered by using forecast price, molybdenum and tungsten equivalent conversion coefficient were calculated, then molybdenum tungsten technical economy indexes of Sandaozhuang open-pit mine were analyzed and calculated. The results indicate due to the tungsten price rises, ores which did not meet the economic stripping ratio could increase benefits for the mine after mining and recovery. Reasonable recycling tungsten could prolong service time and create more profits for mine.

Key words: Molybdenum tungsten polymetallic, Comprehensive development, Technical and economic analysis, Price prediction
