“…The Khibiny fluorapatite is enriched with rare-earth elements (up to 10-12%) [3,10], which is also favorable for luminescence observations [11]. The works [12][13][14][15][16][17] describe successful experience of fluorapatite X-ray luminescence application in lump preliminary processing. Analysis of literary sources [18][19][20][21][22][23][24][25][26][27] has shown the ability of fluorapatite to luminesce not only under the X-ray influence, but when it is irradiated by a UV light (ultraviolet light) source.…”

The article presents the results of the first study stage aimed at analyzing the luminescent properties of the main and minor minerals composing the apatite–nepheline ores and host rocks in the deposits of the Khibiny rock massif (Kola Peninsula, Russia). The main purpose of the work was a search of a stable identification feature providing fast and safe determination of fluorapatite in the mineral mixture of apatite–nepheline ores and solving technological tasks, namely sampling the borehole walls in open pits. The first stage includes studies carried out on pure mono-fractions of four minerals occurring in fluorapatite deposits and possessing obvious luminescent properties: fluorapatite, nepheline, calcite, and sodalite. The authors have revealed luminescence spectra of these minerals and established correlation of their spectral characteristics with the literature data and their consistency. However, the high intensity of sodalite luminescence in a wide band can complicate identification of fluorapatite by the luminescence spectrum in many cases. Therefore, it is reasonable to use the color and intensity of luminescence rather than spectral characteristics.

“…The presence of an increased content of the useful component in screened ore is also typical for some non-metallic minerals. Thus, in the poor apatite-nepheline ores of the Oleniy Ruchei deposit with an average content of the useful component of 5.4%, in the +20 mm grades, the content of phosphorus pentoxide P 2 O 5 was 3.66%, in the ore screening -10 mm -7.22% [12]. In the ordinary ore of the deposit with an average grade of the useful component in the technological sample of 10.1%, in the grades of +20 mm, the content of the useful component was only 5.48%, and in screened ore with a size of -10 mm, the apatite content was 18.05%.…”

In connection with the decline in the quality of reserves of many types of mineral wealth, there is a need to develop mining techniques and technologies that allow for effective development of deposits having increasingly hard mining conditions. In the ores of non-ferrous, rare and noble metals, the concentration of ore minerals in small classes of loosened ore mass is often observed. The paper analyzes the nature of the distribution of gold, tungsten, lead and some other useful components in the original ores, and presents methods for the treatment and primary processing of the ore mass with the separation of enriched classes. An engineering and technological solution has been proposed that provides an increase in production efficiency in opencast mining of deposits, the ores of which, after disintegration, are characterized by the enrichment of small classes, due to the separation of substandard ore siftings in the mine face directly during mining operations, their subsequent sorting and processing, as well as increased productivity and extended functionality of mining equipment. The use of the mining complex when excavating the rock mass will provide a reduction in the cost price, which will allow the complex-structured areas of the deposits to be involved in the development, composed of low-grade and off-balance ores.
