金矿石无捕收剂浮选

无捕收剂浮选是一种新工艺和新的发展方向。作者通过多年的理论及工艺研究，实现了流化钠诱导下的金矿石无捕收剂浮选并已成功地应用于生产之中，这对传统的黄药类捕收剂提出了挑战，使浮选理论与工艺跨入了新阶段。本文从浮选过程的根本特征出发，探讨了金矿石元铺收剂浮选的基本原理，阐述了新工艺的研究过程、结果、应用现状和前景。

COLLECTORLESS FLOTATION FOR GOLD ORES

Collectorless flotation is a new technology and development direction. Through the theoretical and technological research for many years, the authors have achieved the col1ectorless flotation for goldores under the control of Na2S and successfully applied to production,which gives a challenge to the conventlonal xanthate collectors flotation and makes flotation theory and technology to develop into a new stage.Basecl on the fundamental features of flotation process, the basic theory of col1ectorless flotation for goldores is discussed in this paper, and the research results, application status and prospect1ve developrnent ofthe new technology are elaborated.
