| 摘 要： | 针对大厂贫矿石性质，采用ＧＺＤ－Ｉ型动筛跳汰机进行贫矿粗粒预选新工艺的研究，结果表明，将原故破碎分级，其中２０～１２ｍｍ和１２～３ｍｍ两粒级入动筛跳汰机选别，－３ｍｍ粒级作为重产品直接与动筛跳汰机粗精矿合并的工艺不仅合理，且工艺指标好Ｓｎ，ｐｂ，Ｚｎ的回收率分别为９３．３０％，８６．１９％，９０．２３％，抛废率为３８．０３％。

| Abstract: | In the light of the properties of lean ore in Dachang, a study has been carried out on new process for pre-concentrating coarse lean ore by the use of Model GZD- I movable- sieve jig. The results show that the process, in which 20-12 mm and 12-3 mm particles from the crushed and graded run-of-mine are processed in GZD-I, then -3 mm particale, as heavy products, is blended with the coarse concentrate from GZD-I, is not only reason- able, but also provides good process results, with the recovery of Sn 93. 30%, Pb 86. 19% and Zn 90. 23%, and the rate of rejection 38. 03%. |
