Collecting agent improving filtering effect for phosphorite floatation and preparing method of collecting agent

Abstract

The invention relates to a collecting agent improving the filtering effect for phosphorite floatation and a preparing method of the collecting agent. The collecting agent is prepared from, by weight, 10-30 parts of coconut oil, 40-60 parts of palmitoleic acid and 30-50 parts of colza oil oleic acid. The mixture obtained after saponification of the coconut oil, the palmitoleic acid and the colza oil oleic acid is taken as 100 parts, and then 5-8 parts of penetrating type surface active agent is added. The preparing method includes the following steps that 10-30 parts of coconut oil, 40-60 parts of palmitoleic acid and 30-50 parts of colza oil oleic acid are mixed, and the mixture is heated to the temperature of 100-120 DEG C so that the mixture can be sufficiently dissolved and mixed; 150-170 parts of sodium hydroxide is added, and saponification is conducted for 50-70 minutes under the condition of the temperature of 70-90 DEG C; and then the mixture obtained after saponification is taken as 100 parts, 5-8 parts of infiltration type surface active agent is added to be evenly mixed, and therefore the collecting agent improving the filtering effect for phosphorite floatation is prepared. According to the collecting agent, qualified floatation indexes can be ensured, subsequent filtering efficiency of concentrate and tailings can be better improved, it is ensured that the water content of the filtered concentrate and tailings is smaller than 10%, and meanwhile production efficiency is greatly improved.

Description

technical field [0001] The invention relates to a collector for ore froth flotation, in particular to a collector for improving the flotation and filtration effect of phosphate rock and a preparation method thereof Background technique [0002] With the continuous development of the phosphate rock industry, the flotation process, as a low-cost and easy-to-operate process, is currently widely promoted at home and abroad. The quality and cost of ore flotation products are directly linked to the storage conditions of phosphate rock. Years of ore mining have led to gradient differences in the quality of the selected raw ore. Among them, there has been a shortage of raw ore reserves with high grade, coarse particle size and easy stripping. Ore with low density, fine particle size, and severe mudification is gradually favored by merchants due to its cheap purchase and large market capacity. This not only practices the rational use of non-renewable resources, but also greatly reduc...

Problems solved by technology

However, these low-grade, fine-grained ores, and severe muddy ores will cause the concentrate or tailings to fail to filter, and the water content of the filter cake will exceed the standard.

Among them, failure to filter the concentrate will affect the quality of the concentrate, resulting in a decrease in the selling price of the manufacturer; failure to filter the tailings will affect the dry discharge, pollute the environment, and cause a great loss to the filtration equipment
