Hongtoushan Cu-Zn deposit is a typical VMS deposit in Northeast China. To reconstruct the history of the diagenesis and tectonic thermal activities of the area and to investigate the process of the metallogenesis by different approaches are vital to the studies of the deposit. The zircons from biotite-bearing plagioclase ampibolite, a typical host rock of Hongtoushan deposit, were studied to discuss the process of the mineralization of the deposit. The zircons are granular in shape and were formed during the emplacement of the calc-alkaline basalt of the area, the parental rock of the plagioclase ampibolite under this study. According to the results of the analyses in the paper, the zircons were formed at 2500 Ma which represents the age of the Hongtoushan deposit. The deposit was suggested to be formed in a back-arc basin shortly after Anshan movement during which ancient oceanic plates disappeared, continents collided, and granite emplaced. The related thermal activities were responsible for the high grade copper ore pillars in the deposit. Considering the ore-forming processes and the mechanism of the deposit, more attention should be paid to the following two aspects during the exploration of the copper deposit: 1) this type of deposit is hosted in the bimodal volcanic rocks of the greenstone belt; 2) the high grade VMS ores should be localized in the collision belt of continents of the Anshan movement.

With the increase of mine depth, the ventilation is facing great challenges. This paper firstly elaborates the research and status quo of controlled circulating ventilation at home and aboard, and then analyzes its operational principles and introduces application development of the technology in Hongtoushan copper mine. The paper argues that this technology can effectively tackle the problem of ventilation in deep mining and improve the working condition of deep mining by saving energy and reducing consumption. © 2014 The Authors.

chemical compositions, mineral compositions, mosaic relationship, particle distribution characteristics are identified by mineralogy research on oxidization copper ore from Fuxin. Flotation conditions and closed-circuit process is carried out, it is adopted that adding sodium sulfide for sulfiding and ammonium sulfate for activating, then adding sodium silicate and sodium hexametaphosphate as combined inhibitation to intensify inhibitating, a combined collector consisiting of hexyl xanthate and butylamine dithiophosphate was used to strengthen the collecting effect. Finally, a copper concentrate with a grade of 17.39 % and a recovery of 59.36 % can be obtained, meanwhile, the grade of associated silver is 297.8 g/t, the recovery is 55.96 %. © (2012) Trans Tech Publications, Switzerland.
