A discussion of Deswik Pseudoflow Pit Optimization in comparison to Whittle LG Pit Optimization The purpose of this paper is to inform the user about Deswik Pseudoflow within the context of the mining industry's most accepted pit optimization process that uses Whittle software based on the Lerchs-Grossman (LG) algorithm Our passion for progress and innovation has been shaping our laboratory automation systems since 1971 That's when we first introduced QCX solutions to cement producers Over the years we have applied our deep industry knowledge and drive for improvement to develop the QCX/RoboLab range into a complete solution for quality control in cement

Uranium — How Is It Mined?

Open Pit Mining Open pit mining also known as strip mining is the removal of surficial soils and uneconomic rock to get at the ore below Ore grades are normally less than 0 5% This is type of mining is only possible if the uranium ore is near the surface (normally less than 400 ft)
