矿石的高压电脉冲预处理技术研究进展

介绍了澳大利亚昆士兰大学JK矿物研究中心10 余年来在高压电脉冲技术预处理矿石方面的研究进展。该团队没有采用传统的研究思路，将高压电脉冲作为碎磨矿石的工具，耗费大量电能将矿石破碎到微米级的粒度，而是用较小的高压电脉冲能耗来预处理矿石，改变矿石的可选性，以此提高整个选矿处理流程的生产效率和经济效益。目前研发出了3项高压电脉冲在选矿应用的新技术：高压电脉冲用于矿石的预富集，高压电脉冲用于降低矿石硬度、节省碎磨能耗和高压电脉冲用于改善矿物的单体解离。其中，高压电脉冲技术在含金含铜矿石的预富集中的应用属世界上首次发现，介绍此成果的论文获得了有国际影响力的2017年度CEEC科研奖章。

Thoughts on Ways for Energy-Saving and Consumption Reduction in Mineral Processing

Premier Wen Jiabao put forward in the government work report that great efforts should be made to do well the work on energy-saving and consumption reduction and on environment protection. This requires that only by conforming to the basic state policy of energy-saving and consumption reduction can the enterprise exist and develop. The enterprises of mineral processing which is an intermediate link in the energy-intensive metallurgical industry should inevitably consider how to save the energy and reduce the consumption so as to increase their economic benefit and promote their development. The paper, based on the presentation of both the domestic and foreign advanced energy-saving beneficiation equipment and technology in recent years, and the existing industrialized energy-saving beneficiation equipment and technology, proposes the ways for energy-saving and consumption reduction that can be adopted in the concentrator design and transformation, and their practical application cases.
