The analysis and Calculation of phase Diagram of Manufacturing Sodium Bicarbonate or Sodium Carbonate By Trona Carbonation;

Experimental investigation on the removal of organic matter in trona using macroporous adsorption resins

Through laboratory simulatn experiment, a qualitative and quantitative model can be established for the dissolution and corrosion of trona and the formation and expansion of dissolved cavity in deep well water dissolving mining, thereby providing reasonable technical parameters and a scientific method for sinngle_and double_well mining procedure.

Research on screening bioflocculant-producing strains for flocculating the clay in turbid natural soda solution and optimal conditions for production of flocculant;

Application of microbial flocculant in defecating the suspending solution of natural soda;

Optimum conditions for microbial flocculant production to flocculate suspending solution of natural soda;

Theory and practice of solution mining in Wucheng Trona Mine;

Deposition and genesis of the trona deposits in the Anpeng region,Henan

Based on the application of talus well logging technique in extracting wells of trona concession ,this paper approaches the way to accurately determine the horizon of seam and makes detailed analysis on talus fishing,identification of lithologic characters,division of interface,determination of seam and in situ comprehensive explanation.
