How to Get Aluminum from Bauxite Reduction Process

2021-10-28  As the bauxite is found near the surface, it needs an open-pit mining. Step 1- Crushing process. The first step of the Bayer process is to use the crushing equipment to crush the bauxite ore into particles with a diameter of about 30 mm. As the particle size becomes smaller, the specific surface area of the bauxite greatly increases, which ...

Optimized open pit mine design, pushbacks and the gap ...

2014-12-4  Existing methods of pushback (phase) design are reviewed in the context of “gap” problems, a term used to describe inconsistent sizes between successive pushbacks. Such gap problems lead to suboptimal open pit mining designs in terms of maximizing net present value. Methods such as the Lerchs-Grossman algorithm, network flow techniques, the fundamental tree algorithm, and Seymour’s ...
