The technology of microcline for extracting potassium made great developments and contributions to our chemical fertilizers industry. However, the fact that China has so far been seriously short of potassium. In our country ,these techniques have already been studied since 1950' s. Further more , the current developing situation of microcline for comprehensive utilization is not perfect. Although these techniques of microcline for producing potassium fertilizer, molecular sieves, white carbon are very elegant and advanced at present, yet some problems should be solved in the future, such as the sintering temperature is too high , the environmental pollution is very seriously, the fixed investment is so expensive, the silicate bacteria in pure culture conditions is much too long .The advantage and disadvantage of all these processes are compare with each other so that the technological and economical feasibility is examined. At last some suggestions on comprehensive utilization of microcline are present and comprehensive utilization of microcline has much wide application prospect.
