Applied results of the classifying box in concentrator of Lianghe tin mine show that it has the advanced performance,stabilization of classification operation and high classification efficiency.

To investigate the dietary customs and nutrition status, determine the level of development & growth of preschool children living in Tin mine.

The mineralization factors and tectonic evolutionof Dachang superlarge tin deposit, Guangxi, China;

The primary tin deposit in western Nanling is divided into six main types on the base of the analysis of metallogenic characteristics including metallogenic structure type, host rock feature and the difference of orebody shape.

In order to verify the natural radioactivity level of tin polymetallic ore in Southeast Yunnan,and find out radioactive pollution in mining,dressing and smelting processes,10 tin ores in this area were chosen to measure radionuclides’ specific activity in each kind of tin polymetallic ore,undressed ore,ore concentrate,debris and smelting slag.

The technological flow for directly preparing sodium stannate from the low grade tin ore(containing tin 20%￣30%) has been studied.

To investigate influences of mining activities on heavy metal contamination and health risk in vegetable of mining-affected area,the present study was undertaken as a preliminary survey of As,Cd,Co,Cr,Cu,Ni,Pb and Zn concentrations of majority vegetables and soils in area affected by an ancient tin ore,Yunnan province.

A Φ3 m rotary disk concentrator and Yunxi notch shaking table were applied to treat tin tailing slime and rough concentrates or rich middlings were produced.

The inadaptability of spherical media and stick media in fine grinding process of tin ore is first analyzed in this paper.
