Beneficiation of Raw Gypsum Ore

The objective of this project is to design and test proof-of-concept beneficiation processes for H.M. Holloway, a producer of agricultural soil amendments. Beneficiation is the separation of ore constituents into economically valuable components. For raw gypsum ore, beneficiation consists of separating the ore into its three main constituents: gypsum (calcium sulfate dihydrate), clay (calcium bentonite), and quartz (silicon dioxide). Each constituent holds potential economic value as soil amendment to help produce healthier plants and increase crop yield. H.M. Holloway will be considering the results of this project to determine whether it should bring water and utilities to its raw gypsum ore mine location.
