1Role of tannin pretreatment in flotation separation of magnesite and dolomite显示文摘Flotation separation of magnesite and its calcium-containing carbonate minerals is a difficult problem.Recently,new regulat-ors have been proposed for magnesite flotation decalcification,although traditional regulators such as tannin,water glass,sodium carbon-ate,and sodium hexametaphosphate are more widely used in industry.However,they are rarely used as the main regulators in research because they perform poorly in magnesite and dolomite single-mineral flotation tests.Inspired by the limonite presedimentation method and the addition of a regulator to magnesite slurry mixing,we used a tannin pretreatment method for separating magnesite and dolomite.Microflotation experiments confirmed that the tannin pretreatment method selectively and largely reduces the flotation recovery rate of dolomite without affecting the flotation recovery rate of magnesite.Moreover,the contact angles of the tannin-pretreated magnesite and dolomite increased and decreased,respectively,in the presence of NaOl.Zeta potential and Fourier transform infrared analyses showed that the tannin pretreatment method efficiently hinders NaOl adsorption on the dolomite surface but does not affect NaOl adsorption on the magnesite surface.X-ray photoelectron spectroscopy and density functional theory calculations confirmed that tannin interacts more strongly with dolomite than with magnesite.Xiufeng Gong Jin Yao Jun Guo Bin Yang Haoran Sun Wanzhong Yin Yulian Wang Yafeng Fu 2024International Journal of Minerals,Metallurgy and Materials2024,31,3:0
2Management of Intraductal Papilloma of the Breast Diagnosed on Core Needle Biopsy:Latest Controversies显示文摘Intraductal papillomas(IDPs),including central papilloma and peripheral papilloma,are common in the female population.Due to the lack of specific clinical manifestations of IDPs,it is easy to misdiagnose or miss diagnose.The difficulty of dif-ferential diagnosis using imaging techniques also contributes to these conditions.Histopathology is the gold standard for the diagnosis of IDPs while the possibility of under sample exists in the percutaneous biopsy.There have been some debates about how to treat asymptomatic IDPs without atypia diagnosed on core needle biopsy(CNB),especially when the upgrade rate to carcinoma is considered.This article concludes that further surgery is recommended for IDPs without atypia diagnosed on CNB who have high-risk factors,while appropriate imaging follow-up may be suitable for those without risk factors.Siyuan Tu Yulian Yin Chunchun Yuan Hongfeng Chen 2023Phenomics2023,3,2:0
