陕西商南某锑矿选矿试验研究 李素玮1,孙阳1,王建斌1,王红梅1 (1.陕西省地质矿产实验研究所,陕西,西安,710054) 摘要:根据矿石性质进行了锑硫分离回收有价元素锑的选矿试验研究.结果表明:采用糊精抑制黄铁矿,可达到锑硫分离的目的;采用混合型捕收剂,既提高了锑精矿的品位(51.76%),又保证了锑精矿的回收率(76.08%). 关键词:锑硫分离; 黄铁矿; 糊精; 混合型捕收剂; Separation of antimony from sulfur; Pyrite; Dextrin; Combined collector; [全文内容正在添加中] ......
EFFECT OF SODIUM OLEATE ON FLOTATION OF MAGNESITE张志京,毛钜凡摘 要:<正> Laboratory studies were made on the floatabil-ity of magnesite and dolomite ivith sodium oleate asthe collector.The adsorption mechanism of sodiumoleate on the surface of minerals was ex......
and amphibole surfaces was therefore amplified in cleaning, and their further separation became much easier consequently. Key words: rutile; amphibole; flotation separation; combined collector... rutile samples were added to the flotation cell with 40 mL deionized distilled water. After conditioning for 1 min, the pH value of the slurry was adjusted using H2SO4 or NaOH. The collector......
fog collector was prepared by mimicking the back exoskeleton structure of the Namib desert beetle. The improved fog collector was constructed by a superhydrophobic-superhydrophilic patterned fabric via a simple weaving method, followed by in-situ deposition of copper particles. Compared with the conventional fog collector with a plane structure, the fabric has shown a higher water-harvesting rate......
EFFECT OF SOLUTION CHEMISTRY ON THE FLOTATION SEPARATION OF WOLLASTONITE FROM QUARTZ米国民,涂文懋,曾宪滨,李志华摘 要:<正>This paper deals with the flotation separation of wollas-tonite from quartz by using Na-oleate as a collector and metallic ion as anactivator. The reasons why wollastonite is difficult to separate from quartzusing Na-oleate as a collector have......

The pure mineral test shows that oleic acid has a strong ability to collect products... negative zeta potential and the co-adsorption of the collector and synergist at the mineral surface. Infrared spectroscopy demonstrated that when oleic acid and SDBS are used as a mixed collector......
