A kind of complex Copper slag has been studied. The run-of-mine grade of copper was 0.93%. Through the research of the flotation separation test, the optimal grinding fineness (-0.074mm) was about to 75%. The optimum kind and dosage of collector was 150 g/t Y89. The dosage of sodium silicate which was the Slime dispersing agent was 1000g/t. The dosage of sodium carbonate was 800g/t.

FTIR, XPS, and ab initio molecular dynamics studies demonstrated that sodium silicate (Na2SiO3) adsorbs on fluorite with a higher affinity when they are treated beforehand by sodium carbonate (Na2CO3) due to proton exchange(s).

The research has conducted a experimental research on the issues in modifier of flotation process in a molybdenum ore concentrating mill in Inner Mongolia. The results show that: when the raw ore is grinded into 61% -200 meshes, which is the same to the site production ore, the sorting index is optimum in neutral magma condition; and for dispersing agent, the sorting effect of sodium silicate is better than sodium hexametaphosphate, and the confirmed sufficient quality of sodium silicate is 300g/t.

Calgon (a combination of sodium hexametaphosphate and sodium carbonate) has proved to be the most effective dispersing agent in determining the grain size distribution of fine-grained soils by means of the hydrometer analysis. Previous research on the effect of the sodium hexametaphosphate content of dispersing agents on the clay contents showed that the addition of sodium carbonate to sodium hexametaphosphate increases its dispersing effectiveness. Hence, Calgon 35:7 was used /recommended by many researchers/methods and proved to be the most effective dispersing agent. Although previous work focusing on the effect of varying the concentration of sodium hexametaphosphate in Calgon has been reported, the effect of the concentration of sodium carbonate in Calgon has not been assessed and reported. For this reason, in this investigation a series of hydrometer test analyses were conducted using the 152H and ASTM 152H: E100 hydrometers with Calgon in ratios of 35:0, 35:20 and 35:30.  It was observed that with any increase in sodium carbonate content beyond 7 grams, the percentage clay content actually decreased tremendously in the case of hydrometer 152H. However, for the other hydrometer, Calgon (35:0) proved to be most effective combination. Thus, the increase in the sodium carbonate content in Calgon, beyond 7 g/ litre, is not recommended.

The ore from Jingping contains 0.634% nickel, 0.329% copper, 0.047% cobalt, 30.18% SiO2and 19.72% MgO. In order to obtain satisfying beneficiation results, a lot of tests were taken out before, and this article main focus on roughing flotation conditions. Finally find that when the sodium carbonate dosage is 2000g/t, carboxy-methyl cellulose (CMC) dosage is 200g/t, sodium silicate dosage is 100g/t, the combinational effect can depressing the gangue minerals as well as the slime. The final concentration contains 3.03% nickel, 2.01% copper and 2.40% cobalt, the recovery of the nickel, copper and cobalt is 73.03%, 92.58%, 77.62% respectively.

In this study, according to the characteristics of scheelite in run-of-mine, the scheelite was concentrated by adopting the full flotation process with sodium carbonate as regulator agent, sodium silicate as inhibitor for gangue minerals, lead nitrate as activator and ZL pharmacy as collector. 6.15% of the coarse scheelite concentration with tungsten recovery of 96.18% was obtained from the raw ores with grade of 0.86%. The concentration of rough tungsten by heating, by which the high-quality scheelite with tungsten of 62.31% and tungsten concentrate recovery of 93.53% was obtained.
