【摘要】：精選段的礦物粒級(jí)嵌布狀態(tài)愈發(fā)復(fù)雜,粒度越來(lái)越細(xì),給浮選柱的分選帶來(lái)更大挑戰(zhàn)。結(jié)合中色非洲礦業(yè)公司謙比希銅礦的特點(diǎn),考察了KYZE浮選柱的清水動(dòng)力學(xué)性能和分選性能,研究了礦漿循環(huán)泵運(yùn)轉(zhuǎn)頻率對(duì)浮選柱的清水動(dòng)力學(xué)性能的影響,測(cè)試結(jié)果表明選取合適的泵轉(zhuǎn)速和充氣量時(shí),浮選柱液面相對(duì)穩(wěn)定,具有較好的氣液分散性能。研究了循環(huán)泵頻率、充氣量大小和充氣器數(shù)量對(duì)分選指標(biāo)的影響,確定了帶礦試驗(yàn)的關(guān)鍵運(yùn)轉(zhuǎn)參數(shù)。通過(guò)帶礦試驗(yàn),研究對(duì)比了兩種浮選柱的分選性能。研究表明,兩者均能獲取較優(yōu)異的分選性能,滿足選礦廠的要求。KYZE浮選柱的分選指標(biāo)和穩(wěn)定性具有一定優(yōu)勢(shì)。
[Abstract]:The more complex and finer the particle size of the flotation section is, the greater the challenge is to the separation of flotation column. Combined with the characteristics of Champi copper mine in Central Africa Mining Company, the clean water kinetics and separation performance of KYZE flotation column were investigated, and the effect of slurry circulating pump operation frequency on the clean water kinetic performance of flotation column was studied. The test results show that the liquid level of the flotation column is relatively stable and has good gas-liquid dispersion performance when the pump speed and the volume of gas are selected properly. The effects of the frequency of circulating pump, the amount of gas filled and the number of inflators on the separation index were studied. The key operating parameters of the ore bearing test were determined. The separation performance of two flotation columns was studied and compared by ore-bearing test. The results show that both of them can obtain excellent separation performance and meet the requirements of concentrator. The separation index and stability of KYZE flotation column have certain advantages.
