[RESULTS]Open-pitting phosphate mine would greatly damage the ecological environment so to seriously impact on the quality of regional ecological environment in the mine areas, where become a high-risk regions frequent.

Basing on the modern management theory, uniting Hebei Fanshan Phosphate Mine, this paper analyses and dissertates the exterior opportunity and threaten the enterprise faces, as well as the inner predominance and inferior position.

Theoretical analysis of using acidic waste water to float phosphate rock and its practice;

Effect of additive on Jinhe phosphate rock decomposition;

Application of WF-01 collector in flotation experiment of Saudi Arabia phosphate rock;

Relationship between fineness of phosphate ore and its acid hydrolysis conversion rate;

Application of surfactants in low temperature flotation of phosphate ore;

Approaching the flotation and reverse flotation problems of a phosphate ore through particle size analysis (Ⅰ)-tests with fresh water;

Research on acidulation kinetics of P_2O_5, R_2O_3 and MgO in Jinhe phosphorite;

Performance of a two-cycle flue gas desulphurization process using slurries of phosphorite and lime;

Research of new type heavy medium cyclone applied to phosphorite dressing

Taking the Huangmailing Phosphate Mine and Jingxiang Phosphate Mine in Hubei Province as objects of study, this paper analyzes the types of polluting source in phosphate mines and its characteristics, and discusses the effects of ore properties, production processes of mine, area environmental conditions on mine pollution.

By using fuzzy comprehensive judgement method in establishment and determination of basic model and mesunes of coptinuous develpment evaluation in phosphote mines, the author determihes subordinate functrons of different evaluation indexes and indexes' weights and submits the grade divided starndard of continuous development of phosphate mine districts in our country.
