【摘要】:正12月12日,長沙礦冶研究院承擔的"復雜伴生螢石低溫高效浮選技術(shù)"攻關(guān)項目,在湖南省郴州市通過驗收并正式投產(chǎn),這意味著復雜伴生螢石綜合回收這一世界難題在湖南省省獲得重大突破。郴州柿竹園是世界罕見的多種有色金屬富集地,其中伴生螢石資源儲量近1億噸,占全國伴生螢石總量的70%,潛在價值高達2 200億元以上。經(jīng)過前期多金屬選礦后,尾礦含有大量未回收螢石資源,但存在主品位低、雜質(zhì)含量高、多金屬選礦殘余藥劑對螢石浮選效果干擾大等問題,其提純回收成為業(yè)內(nèi)公認難題,曾多次列入國家科技攻關(guān)計劃。
[Abstract]:On December 12, the Changsha Institute of Mining and Metallurgical Research undertook the project "complex associated fluorite low-temperature and high-efficiency flotation technology", which was accepted and formally put into production in Chenzhou, Hunan Province. This means that the complex associated fluorite recovery is a major breakthrough in Hunan province. Chenzhou Shizhuyuan is a rare enrichment area of many kinds of nonferrous metals in the world, among which the associated fluorite reserves are nearly 100 million tons, accounting for 70% of the total associated fluorite in China, with a potential value of more than 2 20 billion yuan. After the early polymetallic dressing, the tailings contain a large number of unrecovered fluorite resources, but the main grade is low, the impurity content is high, and the residual reagent of polymetallic mineral dressing has great interference on the flotation effect of fluorite. The purification and recovery of the tailings have become a recognized problem in the industry. Has been included in the National Science and Technology Program for many times.
