with tungsten and tin mineral. Tungsten is predominately present in wolframite. Tin is predominately present in cassiterite. Adopting chlorination segregation method makes copper mineral phase change, but tungsten and tin mineral phases don’t be changed, thus the copper mineral is separated from tungsten and tin minerals. After the chlorination segregation-flotation-high intensity magnetic separation......

Surface tension of molten Ni-(Cr, Co, W) alloys and segregation of elements XIAO Feng(肖 锋)1, LIU Lan-xiao(刘兰霄)1, YANG Ren-hui(杨仁辉)1, ZHAO Hong-kai(赵红凯)1, FANG Liang(方 亮)2, ZHANG Chi(张 弛)1 1.... The segregation of Cr, Co and W in alloy was calculated and analyzed using Butler’s equation. The results show a good agreement between measured and calculated data. The surface tension of molten Ni-(Cr......
, at the interface formed between L12 and disordered phase, Ni and Al deplete and V segregates. The tendency of segregation or depletion of alloy elements is unchanged with the ordered domain interface because of the solute drag effect, but the degree of segregation or depletion of alloy elements is changed.Key words:Ni75AlxV25?x alloys; microscopic phase-field; ordered domain interface; order-disordered......
