将配比2:1的煤油和柴油混合物,经氧化沉降,分离出羟基酸皂,用作胶磷矿的捕收剂。据对荆襄磷矿王集三层矿和江西朝阳磷矿的试验,均取得了较好的浮选指标。因此可推荐作浮选硅—钙质磷块岩的捕收剂。 (一)药剂的制备 该药剂生产工艺简单(图1),技术指标可靠,原料来源广,取之大庆原油常压切割160～132℃,煤、柴油馏份按2:1混合作为氧化原料,以高锰酸钾为催化剂,在正常温度140～145℃,激发温度150～160℃下,氧化1～2小时,经沉降、脱羟油、皂化即可得成品。
The ratio of 2: 1 kerosene and diesel mixture, the oxidation of sedimentation, hydroxy acid soap was isolated as colloidal collector. According to Jingxian phosphate rock Wangji three mines and Jiangxi Chaoyang phosphate rock test, have achieved good flotation index. It is therefore recommended as a flotation silicon - calcium phosphate rock collector. (A) Preparation of Pharmacy The pharmaceutical production process is simple (Figure 1), reliable technical indicators, a wide range of sources of raw materials, taken Daqing crude oil atmospheric cutting 160 ~ 132 ℃, coal and diesel fractions by 2: 1 mixed as raw materials for oxidation, Potassium permanganate as catalyst, at normal temperature 140 ~ 145 ℃, the excitation temperature of 150 ~ 160 ℃, oxidation 1 ~ 2 hours, the settlement, off the oil, saponification can be finished.
