Abstract
The effects of different factors (composition of the stock, the ratio between the masses of the stock and the sample, time and temperature o f fusion, etc.) on the conditions of microassay preconcentration of no ble metals on nickel sulfide were studied and a method of the quantita tive extraction of noble metals from different natural materials with the subsequent neutron activation determination at the level of n x (1 0(-8)-10(-10))% was developed. Examples of the analysis of natural sam ples of different composition and origin (meteorites, peridotites, chr omites, ores, and rocks) are presented.
