1.	Which of the following statements is correct about the role of substances added in the froth floatation process ?
Answer» Collectors enhance the non-wettability of the mineral particles. Collectors enhance the wettability of gangue particles. By using depressants in the process two sulphide ORES can be separated. Froth stabilisers DECREASE wettability of gangue. Solution :Collectors like SODIUM ethyl xanthates enhances non-wettability of the mineral particles and depressants such as NCN helps to seperate two sulphide ores. For EXAMPLE ore CONTAINING Pbs and ZnS.
