Iron arsenides may be the key to extraction of gold from existing refractory ores such as that at Bakyrchik, Kazakhstan, an ore body containing an estimated £8.5 billion reserve of gold. Gold is not extractable without significant ecological contamination from the associate arsenopyrite mineralisation. A new method for gold recovery from refractory The deposit has 280 t (since 2014 of ore estimation) of gold reserve with average 7.7 g/t in a gold containing carbonaceous-sulfide ore formation. The highest amount of gold-bearing sulfide minerals are localized in siltstones with 0.2 0.4% carbon and presence of the carbonates and the total sulfide content of the ore varies from 0.5% to 10%.Major Mines & Projects Kyzyl (Bakyrchik) Mine

Crushing and Grinding Process JXSC Machine. The ore size reduction process involves two steps: crushing and grinding. The grinding process is the final operation of making the mineral to dissociate from the monomer and making the particle size meet the selection requirements. Grinding is a high-efficiency and low-efficiency operation.Other process routes can require its separation by physical techniques prior to oxidation, as is practised at Bakyrchik, or the use of an additional carbon passivation technique, such as the use of CIL to treat carbonaceous BIOX ® product, at Sansu. 7.5.

Ore medium crushing is a process of crushing ore blocks with a feeding particle size of 125–400 mm to 50–100 mm. The maximum crushing ratio of medium crushing is about four. The force in the process of ore crushing is mainly crushing and impacting. The main equipment suitable for medium crushing operations is a jaw crusher, The gold deposits at Bakyrchik consist of a series of mineralized lenses or lodes lying within a large shear zone, Turquoise Hill Resources News Releases GOLD PRODUCTION BAKYRCHIK MINE, KAZAKHSTAN --- Ivanhoe Mines' President Daniel Kunz and General Director of the Bakyrchik Mining Venture Jaime Troncoso announced bakyrchik gold mine

Most of the high-grade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (−31.5 + 6.3 mm) and fines (approximately −6.3 mm) products.
