Sulfidization regulation of cuprite by pre-oxidation using sodium hypochlorite as an oxidant被引量：6
《International Journal of Mining Science and Technology》2021年第6期1117-1128,共12页Guang Han Shuming Wen Han Wang Qicheng Feng 
the Project funded by Ten Thousand Talent Plans for Young Top-notch Talents of Yunnan Province (Grant No. YNWR-QNBJ-2018-051)。
The direct sulfidization of cuprite is inefficient because cuprite is a copper-oxide mineral with a strong surface hydrophilicity.In this study,oxidant was used to modify cuprite surfaces to regulate the sulfidization...

Enhanced sulfidization flotation of cuprite by surface modification with hydrogen peroxide被引量：11
《Transactions of Nonferrous Metals Society of China》2021年第11期3564-3578,共15页Guang HAN Shu-ming WEN Han WANG Qi-cheng FENG 
Project funded by Ten Thousand Talent Plans for Young Top-notch Talents of Yunnan Province, China (No. YNWR-QNBJ-2018-051)。
Hydrogen peroxide was used as an oxidant to modify the cuprite surface and enhance its sulfidization.Surface-adsorption and infrared spectroscopy measurements indicated that the modification of the cuprite surface wit...
