In this situation, it is possible to have too little froth area, making froth removal the rate-controlling step in the flotation process An extreme example of this occurs where the largest available cells are not suitable due to froth area limitations, yet may satisfy the old lip length rule...
What is the role of depressant in froth floatation process? Answer In the froth floatation process, the role of the depressants is to separate two sulphide ores by selectively preventing one ore from forming froth For example, to separate two sulphide ores ZnS and Pbs , NaCN is used as a depressant which selectively allows PbS to come with ....
