Впервые метод комбинированного электропрофилирования был предложен в 1937 г. А. С. Семеновым. Проведенные им и Н. П. Григорьевой лабораторные и полевые экспериментальные работы показали высокую эффективность метода при поисках хорошопроводящих крутопадающих рудных тел, залегающих в электрически однородной среде.
В Центральном Казахстане на месторождениях кварцево-молибденовой формации широко развиты процессы выщелачивания молибдена из зоны окисления. Особенно интенсивно выщелачивание молибдена проявлено на выходах молибденоворудных кварцевых жил, т. е. в самой приповерхностной части рудных тел, на глубине в несколько десятков сантиметров. При этом вблизи поверхности на месте молибдена остаются пустоты выщелачивания и повелит, который трудно поддается визуальному определению.
Радиоактивные методы, обладающие высокой степенью чувствительности, могут найти широкое применение при поисках и разведке месторождений, в которых радиоактивные элементы находятся в подчиненном или вообще непромышленном скоплении. Ниже описываются результаты исследований применимости радиоактивных методов (радоновой съемки) при поисках свинцово-цинковых месторождений.
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.
Quantitative determination of elements in rocks and ores is widely carried out on the basis of chemical and physicochemical methods of analysis. Physicochemical methods in quantitative analysis are mainly represented by spectral and polarographic methods. The luminescent method is utilized for these purposes mainly as a special method of quantitative mineralogical analysis [1]. Quantitative mineralogical analysis with the use of the luminescent method is based on the property of luminescence of some minerals when irradiated with cathode, ultraviolet and X-rays. Thus, based on the use of cathode luminescence of scheelite, its quantitative determination in scheelite ores and concentrates is carried out [2].
Prospecting for polymetallic deposits in the conditions of Kazakhstan is very difficult in areas of smooth relief and widespread development of eluvial-deluvial deposits. Here, prospectors primarily deal with loose deposits, under the cover of which bedrock is hidden. Additional complications in searching for polymetallic deposits from the surface arise due to the fact that these deposits usually have a deeply worked oxidation zone, as a result of which primary sulfide minerals are mostly transformed into super-sulfide ones. Oxidized sulfide ores, having increased porosity, are very easily subjected to further mechanical destruction, turning into loose finely dispersed formations.
