Võ Quang Bình, Phạm Quang Thắng

The amelioration of sample division instrument made before the realization of the Project “Survey and evaluation of the prospect of titanium-zircon placers in the red sand formation in Ninh Thuận, Bình Thuận and North Bà Rịa - Vũng Tàu areas” is a technical work of both scientific and economic significances. It has been serving effectively the work of shortening samples of this Project; samples have been mixed and divided quickly, regularly and precisely.

In this article, the authors present studied problems in the new case of sample division ameliorated from the traditional case, at the same time, set forth some experiences aiming to raise the effectiveness in the use of the new ameliorated case.
