USING THE INTEGRAL INDICATOR TO DETERMINE TI-ZR PRIORITY AREAS OF PLACERS

The article presents the author’s method of selection of priority areas of Ti-Zr placers using an integral indicator. As you know, the integral indicator is the ratio of the total beneficial effect from the development of the deposit to the total costs of operation, it is calculated as the difference between the value of conventional ilmenite (according to the US Geological Survey) (Mineral Commodity..., 2023) and the cost of obtaining overburden and processing the productive layer. Based on the methodology developed and presented in the article, an experiment was conducted on the data of one of the placer deposits located within the Ukrainian placer sub-province. It is proposed to develop it in small blocks that ensure high productivity, minimal impact on the environment and allow replenishment the mineral and raw material base of the titanium industry of Ukraine. This technique can be used at any deposit of titanium-zirconium ores both in Ukraine and abroad.
