The separation of monazite from zircon by flotation
1972年10月1日 Monazite can thus be activated by Na;>S and responds well to soap flotation, whereas zircon does not. The amenability of monazite and zircon to alkyi sulphate and amine flotation is predictable from Figs. 5 and 6. Comparison of Figs. 3-6 reveals that the adsorption curves for SDS and DA are of a different nature from those for OLH.

Reappraisement and refinement of zircon U-Pb isotope and
2010年5月21日 A protocol was established for simultaneous measurements of zircon U-Pb ages and trace elements by LA-ICP-MS at spot sizes of 16–32 μm. This was accomplished by introducing N2 into ICP to increase the sensitivity. The obtained U-Pb ages for zircon standards GJ-1, TEMORA and SK10-2 are consistent with the preferred values within

The separation of monazite from zircon by flotation
1972年10月1日 The results obtained indicate that sodium sulphide affects the soap flotation of monazite and of zircon differently, hence it is useful in obtaining a high degree of selective separation. On the other hand, sodium sulphide is without selective action in alkyl sulphate and amine flotation. It seems that SH − and S 2− ions are adsorbed ...
