Silica sand and quartz represent the second most common mineral in the earth's crust. The silica-water interface is central to the processing of a large number of mineral systems and the flow properties of particulate suspensions. In particular, these flow properties define the upper limit to processing of tailings suspensions in the mining industry and, ultimately, the recovery of water. In some regions of the world, the scarcity of fresh water has pushed this industry to use seawater, either as is or partially desalinated. Here we analyze the impact of monovalent alkali metal chlorides that are typical of seawater on the viscoelastic behaviour of flocculated silica sediments at concentrati..View full abstract
