The iodine value generally was applied to present the saturation of fatty acid. In this paper, the fatty acid with different iodine values from soybean oil were prepared by surfactant extraction. The collophanite flotation behaviors using sodium fatty acids with different iodine values as collectors were explored.

The strength of the cyanide solutions is tested by silver nitrate, using 10 c.c. of the strong and weak solutions respectively (diluted to about 100 c.c. with water) and taking 100 c.c. of wash-water undiluted. In each case a few drops of a 5 per cent, solution of potassium iodide are added. When the titration is done very rapidly and carried ...

Sodium sulfide is one of the most widely used alkali metal sulfides in the flotation of copper, lead, and zinc minerals in their oxidized form. The sulfidization process, developed in the U.S.A. in 1915-20 for oxide copper minerals flotation, is especially suitable for oxidized lead ores in which the gangue is usually basic.

0.3 g solution was weighed to the accuracy of 0.0002 g and placed in 250 mL iodine flask. Then 30 mL of water was added to dissolve the sample, and 4 g of potassium iodide was added. The mixture in the iodine flask was shaken, sealed with water and allowed to stand in the dark for 30 min. 2 mL of glacial acetic acid solution and 25 mL of …

Abstract. An increasing demand for lithium-ion batteries is driving the development of new lithium mineral projects. Spodumene, a major lithium-bearing mineral found in pegmatite deposits, is often recovered by froth flotation. The primary collectors in spodumene flotation are fatty acids which are known for their poor selectivity.

Froth flotation is a complicated process which is difficult to establish its first-principle model. Due to the fluctuations in the grade of raw ore, adaptively adjusting the set-points is extremely important in the flotation process. The inappropriate set-points easily lead to the instability of the process. This paper presents a fuzzy association rule-based …
