摘要

Tronox KZN Sands Hillendale矿山位于祖鲁兰，靠近理查兹湾。采矿活动于2001年开始，该矿于2013年结束生产。在Hillendale，开采了高细粒含量的沙丘，回收了钛铁矿、锆石和金红石等有价值的矿物。以粘土矿物为主要成分的细粒馏分在渣油贮存设施中进行了处理。在停止采矿活动之后，已为实现关闭地雷而执行了若干行动。本文首先介绍了作为Hillendale矿山一部分的渣油设施运行的一些基本背景。其次，本文将重点介绍在RSF计划和实施的矿山关闭活动。从Hillendale矿山获得的经验和教训将成为Tronox在Fairbreeze新建立的矿山中运营的RSFs未来关闭计划的基础。

Rehabilitation of the Hillendale Mine’s residue storage facility

The Tronox KZN Sands Hillendale Mine is located in Zululand – close to Richards Bay. Mining activities commenced in 2001 and the mine’s production came to an end in 2013. At Hillendale, dunes with a high fines content were mined to recover the valuable minerals of ilmenite Zircon and rutile. The fine fraction consisting mainly of fine clay minerals was managed by storage in a residue storage facility (RSF). Following the cessation of mining activities several actions have been implemented towards achieving mine closure. This paper will firstly give some basic background on the operation of the residue facility as part of the Hillendale Mine. Secondly the paper will focus on mine closure activities planned and implemented at the RSF. The learnings and experience gained from the Hillendale Mine will form the basis of future closure plans for RSFs operated as part of Tronox’s newly established mine at Fairbreeze.
