Gypsum Processing | Equipment, Process Flow, Cases
Most of the world's gypsum is produced by surface-mining operations. In the United States, gypsum is mined in about 19 states. The states producing the most gypsum are Oklahoma, Iowa, Nevada, Texas, and California. Together, these states account for about two-thirds of the United States' annual production of gypsum.

Terminal Velocity of Particles for Gravity Separation
Analysis of gravity separation is undertaken by first starting with a force balance on a single particle. The two primary forces in the system are gravity and drag. Gravity acts to pull the heavier component down while drag is experienced by a particle as it moves through a fluid, and acts in the opposite direction to the particles direction of ...
