Abstract : the development of main mineral processing technologies of wolframite and scheelite are presented in the paper 文摘:分別介紹了黑、白鎢選礦工藝主要技術進展情況。
Is a hard , brittle , corrosion - resistant , gray to white metallic element extracted from wolframite , scheelite , and other minerals , having the highest melting point and lowest vapor pressure of any metal 顏色呈灰色或棕黑色,硬度高,延性強,熔點極高,常溫下不受空氣侵蝕主要用途是制造燈絲和高速切削合金鋼,各種鎢電極,也用于光學儀器,化學儀器方面。
Improved hand picking technology greatly enhance the mineral processing tate of waste in many dressing plants . the flotation in normal temperature is a big breakthrough in mineral processing technology of scheelite . improved jig sizing applied in roughing and grqvity dressing , and improved tungsten fine deposit recovering technology enhance the recovery of tungsten fine deposit 手選工藝的改進,使各選廠的廢石選出率得到大幅度地提高;常溫浮選是白鎢選礦工藝的重大技術突破;推廣并改進動篩跳汰使這在粗、重選中獲得應用;鎢細泥工藝的改進提高了鎢細泥的回收率。
The main conclusions with innovative features acquired from the present work are as follows : ( 1 ) soft solution processing technique for preparing functional thin films was put forward and applied to preparing advanced inorganic functional thin films ; a series of molybdate and tungstate films with scheelite - type were prepared directly on metal substrates ( molybdenum and tungsten foils ) by using constant current electrochemical technique at room temperature ; a series of titanate thin films with perovskite - type were synthesized directly on titanium flakes by hydrothermal method in our country for the first time 通過上述研究工作,得到了如下具有創(chuàng)新性研究成果: ( 1 )首次在國內提出和運用軟溶液制備工藝技術進行無機功能薄膜材料的制備研究;首次在國內采用室溫恒電流電化學技術直接在金屬基底(鉬片和鎢四川大學博士學位論文片)制備了白鎢礦結構的鋁酸鹽、鎢酸鹽薄膜;首次在國內采用水熱合成技術在欽金屬片上直接沛叮備了鈣欽礦結構的欽酸鹽薄膜。
