Role of sodium carbonate in scheelite flotation – A

2018-12-1  Indeed, Cooke (1949) showed with the bubble pick-up method that the activation of quartz for flotation through the calcium ions in solution was given by the expression (concentrations in mol/l): C a 2 + = H + × 10 6 + N a + × 10-3. Hence, the addition of sodium carbonate and therefore, of Na +, reduces the probability that Ca 2+ activates ...
