Based on the analysis of the main existing problems of the beneficiation flowsheet of Shanghai Meishan Mining Co. 's concentrator,suggestion is made on the orientation of the scientific research of tackling the keyproblems in optimizing the beneficiation flowsheet and summary is made on the achievements obtained.
The mineral processing flowsheet, production equipment and commissioning test run indexes of Fanshan Apatite Mine are introduced with the emphasis on the remake of feeders,flotation machines, feed pipeline, soIution drainage facility of vacuum filtering system, the technology adjustment for achievement of designed production indexes and the current economic and technolngical indexes.
The beneficiation index is improved, quality and output of the product are stably increased through technical transformation of mineral processing flowsheet and import of new beheficiation equipment. Tentative ideas on further perfecting technological flowsheet are also presented.
Based on the sampling design for Ta/Nb ore dressing flowsheet and sampling operating practice,the paper investigated the problems and their solutions during the RE ore deposit samping design and sampling operation.
