秘鲁安塔米纳(Antamina)矿海拔高度超过4300m,属多金属矽卡岩矿,从设计至生产面临一系列挑战。安塔米纳磨矿回路由一台半自磨机和3台球磨机组成,批量处理多种矿石。在回路设计及设备选型时主要考虑到矿石性质变化大。本文探讨了磨矿回路设计思路及5年的生产实践经验,着重研究了回路的适用性。
The Antamina mine in Peru is more than 4300m above sea level and belongs to the polymetallic skarn mines. There are a series of challenges from design to production. Antimina grinding circuit by a semi-self-mill and three ball mill composition, batch processing a variety of ore. In the loop design and equipment selection mainly consider the great changes in the nature of the ore. This paper discusses the design of grinding circuit and five years of production experience, focusing on the applicability of the circuit.
