Abstract
Problem Statement (Relevance): The paper describes the features and potential benefits of gold recovery from pyrite concentrates using microwave technologies. We made calculations and obtained the theoretical results using the example of the Gaiskoye deposit. Objective: The objective is to improve the efficiency of recovering gold from pyrite heaps, and to increase the mineral resource base of the Urals. Methods Used: The microwave technology was used to heat minerals of waste rock and crack the shell, and then gold particles may be recovered. Novelty: The elements of novelty include the improvement of calculation methods, showing an increase in the recoverability of gold and silver. Findings: The paper presents a comparison of methods and the use of microwave technologies in relation to the deposits in the Southern Urals, in particular, the Gaiskoye deposit. We made the calculations showing an increase in the efficiency of noble metal recovery using microwave technologies. Practical relevance: These calculations will contribute to a comprehensive processing of refractory gold-bearing ores, thereby improving the environmental situation in the Southern Urals.
