The temperature field in a hollow cylinder due to a source moving along a helix

AbstractWe solve the problem of the temperature distribution in a hollow cylinder due to a source moving along a helix on the outer surface with boundary conditions of the second kind. The solution can be used to calculate temperature fields on a computer for various forms of processing materials.

Acid bake-leach-flotation treatment of offgrade molybdenite

AbstractA process has been developed and piloted to reject Cu, Pb, Fe, P, Bi, Sb, elemental sulfur, and insol from molybdenite concentrate without decomposing the contained molybdenite and rhenium. The impure concentrate is first heated with concentrated sulfuric acid to attain a 260? to 290?
