Zhen'an Tungsten Ore Dressing Plant Project under the EPC of CIE Has Realized Continuous and Stable Trial Production
Recently, the Zhen'an Tungsten Ore 1000 tons/day Dressing Plant Project of Shaanxi Cheng'an Mining Development Co., Ltd. (hereinafter referred to as "Zhen'an Tungsten Ore Dressing Plant Project"), which was constructed by CIE as the EPC contractor, has been in continuous and stable trial production for one and a half months since the successful on-load test run in mid-September. The tungsten concentrate grade reaches 56%-67%, exceeding the design index, marking the staged major achievements in the construction of Zhen'an tungsten mine and laying a solid foundation for the whole line to reach the design capacity and standard.
Relying on Dongyang Tungsten Mine in Zhen'an County, a large tungsten mine, this project proposes to build a 300,000 t/a tungsten mining and beneficiation production line. The project attaches great importance to energy conservation, safety and environmental protection. After comparison and selection, the beneficiation process is determined as the full gravity separation process of "three-stage crushing and screening with a one-stage closed circuit, ore washing and desliming, two-stage grinding stage separation, spiral tailings dumping and shaking table cleaning". At the same time, energy-saving equipment is preferred, and the plant is provided with stage layout and compact configuration, which meets the requirement of reasonable exploitation and utilization of tungsten ore resources in green mines, and achieves the purposes of water conservation, electricity conservation and land conservation, and creates a win-win situation of local eco-friendly and sustainable development.
