The use of power ultrasound in mining. L. Gaete-Garretón, in Power Ultrasonics, 2015 35.5.1 The flotation process. One of the most used processes to concentrate mineral from a mine is flotation. To perform a flotation process the mineral is finely ground (particle sizes between 50 and 150 μm), then the ground mineral is mixed with water in a container called a flotation cell.
1. Introduction. Mining activities consume billions of m 3 of water annually. The water withdrawn by mining industries could achieve 17 m 3 per ton of processed ore while the water consumption required in processing varies between 0.34–6.27 m 3, according to data from 359 industries reports [1].Seeing that the world iron ore production was 2537 million tons in …

Blending of different ore types in the concentrator feed contributes significantly to maintaining a high recovery of valuable minerals with required grades in the concentrate. It is feasible to develop an ore-blending scheme over the life of a mine already in the design phase of the plant. In addition to ore characteristics, water quality is known to impact mineral recovery. …
