the processing of oolitic hematite is considered to be one of difficult problems in mineral processing due to finely disseminated and complex structure of ore. The ore property, size distribution, mineralogy and mineral processing technology of refractory oolitic hematite in Longyan Iron Mine of Xuan Steel in Hebei, China is studied in the paper.. The result shows that grade of iron concentrates of 61.34 % and the recovery of 53.07 % are obtained by four stages of grinding, four times of gravity, tertiary HMS and single stages of rougher and scavenger reverse flotation in sequence.

This article conducts mineral processing experimental study on a certain iron tailing ore in Hebei. According to the ore characteristics, the final flowsheet of stage grinding - weak magnetic - strong magnetic - anionic reverse flotation is determined to sort the ore. Under the conditions that grinding fineness is -200 mesh accounting for 60.0%, collector is butyl xanthate and activator is copper sulfate, this test can obtain zinc concentrate that grade is 36.25% and recovery is 84.15%

Aiming at the problems of large temperature differences and inconsistent baking speeds at different positions in the tobacco chamber of the tobacco baking room, this paper proposes a complex structure processing technology of fan vent. according to the structure and drying principle of the baking room, ANSYS fluent simulation software was used to analyze the processing parameters of the heat flow field inside the baking room. combining the characteristics of positive and negative air supply baking, the processing and manufacturing parameters of the baking room were optimized, and then the baking comparison test was performed. The results show that: the forward and reverse air-baking method and the complex structure reduces the temperature difference in the interior of the smoke chamber; the forward and reverse air-bake method reduces the baking time by 11 hours, and reduces the coal consumption and power consumption by 12.6%, 48.5%, the standard deviation of temperature monitoring points in the baking room decreased by 44%.

The composition of catering waste oil is similar to that of traditional materials for the preparation of fatty acid collectors, which makes it possible to change catering waste oil into fatty acid collector applied to ore flotation. The collectors which come from catering waste oil are detected by FTIR and GC-MS analyses. The FTIR date shows that collectors contains lively carboxyl functional groups and The GC-MS date reveals that those carboxyl functional groups exist in single unsaturated fatty acid and three unsaturated fatty acid. The collectors can be applied to iron ore reverse flotation, apatite flotation, and fluorite flotation. It has better flotation experiment results than the traditional collector that using in field production.

In order to resolve the problem of fine particle flotation in the reverse flotation of bauxite. a new method of intensifying secondary concentration technology was firstly advanced, and author applied it to ore, achieved eximious experimentation index. The reverse flotation tests of intensifying secondary concentration aiming at bauxite from Guizhou province were studied. The results show that diaspore concentrate directly used in the Bayer-mineral processing method can be obtained by using the intensifying secondary concentration technology without pre—desliming. The average A/S of the concentrate is 10.28 with a recovery rate of 85.41%.
