Development of Underground Gold Processing Plants
Development of Underground Gold Processing Plants Underground gold processing plants have potential advantages over traditional surface installations related to a smaller environmental footprint, reduced capital and mining costs, improved security and increased value of the product delivered to surface. The concept of processing gold ores on the surface is the traditional paradigm. A process of pre-concentration of ore underground is likely to result in a major shift in operating costs. In particular, run of mine ore or a large proportion of it will not need to be transported to the surface. As a result, environmental and financial benefits are likely. Underground plants are likely to be pre-concentration systems where the process product is a high-grade concentrate and tailings for stope backfill._x000D_
Units will be either static or modular. Concentration methods will be gravity and/or flotation or leach based. This paper discusses the development underground gold plants from early concept, through to the world's first operational unit, a newly commissioned unit and the technical basis of a fully modular system.
