Froth floatation process

Froth floatation :

Oil used as frothing agent in froth-floatation process is

Which of the following statements is correct about the role of substances addedd in the froth floatation process?

Which of the following statements is correct about the role of substances addedd in the froth floatation process?

Statement - 1 : Sulphide ores are concentrated by froth floatation process. And Statement - 2 : Pine oil acts as a frothing agent in froth floatating process.

Which of the following statements are true for froth floatation process (for a concentration of sulphide ores)?

Chemical used as a depressant in separatin ZnS from PbS in froth-floatation process , is

A: Cuprite is concentrated by froth floatation process R: Cuprite is the sulphide ore.

One of the processes used for concentration of ores is Froth floatation process. This process is generally used for concentration of sulphide ores. Sometimes in this process we add NaCN as a depressant. NaCN is generally added in case of ZnS and PbS minerals. what is the purpose of addition of NaCN during the process of Froth floatation?
