In order to solve the problems of a slow solving speed and easily falling into local optimization an ore-blending process model (of polymetallic multiobjective open-pit mines), efficient scheduling method based on multiagent deep reinforcement learning is proposed. Firstly, according actual production situation mine, optimal control for ore blending was established with goal minimizing deviatio...

Purpose. In order to fully exploit the metal and facilitate its method of processing, we need an accurate knowledge composition, granular distribution, association with unimportant penalizing elements that would like get rid of, compared distribution element extract by flotation method. Methodology. The present experimental work proposes approach mineralogical, chemical particle size characteri...

The massive sulfide deposits (VMS) from Mănăilă are associated with the metamorphic formations of Tulgheș Lithogroup Bucovinian Nappes Crystalline-Mesozoic Zone in Eastern Carpathians, Romania. following types ore were identified: pyrite-polymetallic, pyrite copper, compact and precompact quartz-precompact copper. polymetallic mineralization consists pyrite, chalcopyrite, sphalerite, galena, su...

Antimony deposits contain little Sn, whereas Sb and Pb are not the principally contained metal of granite-related Sn deposits. The Danchi Sn-metallogenic ore belt (DSOB) in southwestern China is characterized by Sn-Sb-Zn-Pb co-enrichment, yet triggers poorly constrained. Beixiang deposit southern DSOB consists stage I Sn-Zn II Sb-Pb-Zn mineralization. Here, we analyzed cassiterite U-Pb age, flu...

To reveal the genesis of Makeng-style iron polymetallic deposits from SE China in paleo-Pacific tectonic domain, a new analytical method LA-ICPMS garnet U-Pb dating and rare Earth element analysis was conducted for Makeng, Luoyang, Dapai Pantian deposits. The results nine skarn samples these suggested that mainly formed during 137–130 Ma, which is consistent with zircon molybdenite Re-Os ages. ...
