随着我国科学技术水平,特别是采矿、选矿和冶炼技术水平与生产管理水平的不断提高,以及国际市场黄金价格的不断上涨,回收较低品位的金矿资源是完全可能和现实的。因此,降低现行边界品位和矿块最低工业品位等圈矿工业指标,重新评价现已探明的金矿资源和正在生产的黄金矿山,增加其储量,扩大矿山规模,是当前加速黄金生产建设的重要途径之一。本文是对现在正在大规模生产的金厂峪金矿床降低工业指标的探讨,借以重新评价该矿床,促进其两翼和外围找矿勘探工作的发展,从而扩大该矿山的生产规模。
With the level of our country’s science and technology, especially the increasing level of mining, beneficiation and smelting technology and production management, as well as the continuous rise of the gold price in the international market, it is entirely possible and realistic to recover low-grade gold resources. Therefore, it is the current acceleration of the gold production and construction to reduce the existing border grade and the lowest industrial grade ore block industry indicators, to re-evaluate now proven gold resources and gold mines are being produced to increase its reserves and expand the scale of mines One of the important ways. This article is a discussion on the reduction of industrial indicators of the Jinchangyu gold deposit currently under mass production to re-evaluate the deposit and promote the development of prospecting work on both wings and periphery so as to expand its production scale.
