The development of bauxite projects is focused primarily on such important aspects as incountry available infrastructure, logistics, mineral processing, or deposit geology. These disciplines play an important role by having significant impact on project economic viability, technical feasibility or the capacity to raise funds for project development. Nevertheless, when all these important aspects are finally determined, the project still needs to deliver quality and profit-generating product, therefore a study should be undertaken to incorporate appropriate mine planning techniques to determine the product quality range. It should define the bauxite product quality achieved from the deposit over the Life of Mine period and how this aligns with the project’s strategic objectives in terms of project minimum mine life or head grades. Some fundamental factors, known as Mining Modifying Factors, will influence the production profile and hence should be appropriately incorporated to the study at an early stage. These modifying factors include mining dilution and recovery, processing recovery, cash costs, and their effect on the economic value of a mining block. They are inherently linked to the deposit characteristics, the mining method to be applied, in situ grades, strip ratio, and other technical or economic characteristics influencing the quality of the final product.

Possibilities here are practically unlimited and should be defined on a case by case basis, but, from the Hengyang’s experience, it is usually the case that very little of the required input information is available at the Scoping Study or Preliminary Economical Assessment stage when developing bauxite projects. In such cases it is common to use benchmarked values. This exercise can, however, be successfully implemented in operating mines as part of their long term mine plans. Obviously, different sets of the input parameters will be required for a bauxite export operation than for a bauxite mine with an integrated alumina plant

Hengyang Industry is an Chinese Company based in Zhengzhou city that manufactures, on proprietary technology, plants and equipment for waste recycling and recovery with energy production, material recovery or production of finished goods.

Innovation, R&D, passionate and skilled team along with the customer satisfaction have always been the success of Hengyang and they still are the peculiarities of our Company.
