NaCN is sometimes added in the forth floatation process as depressant when ZnS and PbS minerals are expected because :

A

`0.84`

B

`0.54`

C

`0.42`

D

`0.64`

Text Solution

Verified by Experts

The correct Answer is:
1
`(M_(mix))/(M_(H_(2)))=25`
`M_(mixture)=50`
`{:(N_(2)O_(4)(g),hArr,2NO_(2)(g),,),(a,,,,),(a,,2aalpha,,):}`
`axx92=50xxa(1+alpha)`
`alpha=(42)/(50)=0.84`

NaCN is sometimes added in the froth flotation process as a depressant when ZnS and PbS minerals are expected because :

The incorrect statement regarding forth floatation process is

When ZnS and PbS minearls are present together, then NaCN is added to separate them in the froth floatation process as a depressant, because :

State the role of depressant in froth floatation process.

When ZnS and PbS minerals are present together, Then NaCN added to separate them in the froth floation process as a depressant, beacuse :-

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?

What is the role of depressant in froth floatation process?

Why is thie that only sulphide ores are connectrated by forth floatation process ?

The chief ore of Zn is the sulphide ZnS. The ore is concentrated by froth floatation process and then heated in air to convert ZnS to ZnO 2ZnS+3O_3 rarr 2ZnO+2SO (80% conversion) ZnO+H_2SO_4 rarr Zn SO_4+H_2O (100% conversion) and 2ZnSO_4+2H_2O rarr 2Zn+2H_2SO_4+O_2 (80% conversion).The number of moles of ZnS required for producing 2 moles of Zn will be :

(a) Write the principle of method used for the refining of germanium (b) Out of PbS and PbCO_(3) (ores of lead), which one is concentrated by froth floatation process preferably ? (c) What is the significance of leaching in the extraction of aluminium ?
