Yesterday, we tested the method on recovery of lead from lead sulphate. It was a total failure. We mixed the lead paste and sodium carbonate at a 1:1 weight ration instead of mole ratio. Then we use the welding kit to burn. It forms a layer of dried metal. Judging from the color, i suspect it is red lead and yellow lead, as there was a lot of such materials forming up....zzzz But i saw some parts of the mixture turn silverish, which i can safely presumed that it is lead. haiz.....
How, what to do..... we are so dead!! Why can't our big boss gib us the project on the raw ore and extract lead and zinc from it since from what i heard is using simple and cheap components...zzz WTF
Will write more but for now, need to do clean up as there are some inspectors coming to check the area.
Next time then
