A simplified method for the selection and processing of metallometric samples in the search for lead deposits

Abstract

Plumbometric survey is widely used in prospecting for lead deposits in Central Kazakhstan. Work carried out at several polymetallic deposits in Central Kazakhstan in 1951-1953 established the possibility of significantly simplifying the sampling and processing methods. A simplified method for sampling and processing metallometric samples is proposed for prospecting for lead deposits, which consists of selecting a class smaller than 0.1 mm by sieve analysis, which is directly sent for analysis. This method significantly speeds up, simplifies and reduces the cost of metallometric survey work. The applicability of the described method should be tested at other deposits, where, during the formation of eluvial-deluvial deposits, minerals containing a valuable component pass into eluvium and deluvium in the form of ocher and finely dispersed formations. In 1954, the author demonstrated the applicability of this method in the conditions of Central Kazakhstan when analyzing samples from eluvium-deluvium for zinc, copper and molybdenum.
