An Ore, Consisting Mixture Of Quartz And Feldspar
An Ore, Consisting Mixture Of Quartz And Feldspar

An ore, consisting mixture of quartz and feldspar is to be separated by flotation of quartz. In this ore, all particles of quartz and feldspar are pure minerals none of the grains are locked. The rate of flotation of feldspar is governed by a first order rate process, with k being the rate constant.
