The structure of the hydrocyclone is relatively simple. Its upper end is a cylindrical part, and its lower part is a conical container. The slurry is fed into the cyclone at a certain speed (generally 5 to 12 meters per second) along the tangential direction, and obtains a rotary motion, thus generating a large centrifugal force (usually tens of times or even hundreds …
Vale and Minerals partnered to optimise the desliming stage at Vale's Vargem Grande 2 Plant (VGR2), located near the town of Nova Lima in the state of Minas Gerais, Brazil. The average iron ore slimes losses at VGR2 corresponded to approximately 18% by weight of the total iron ore mined, totalling 1.9 million tons of iron lost every year.
