This explains the lower collector concentration required for the flotation of quartz compared to hematite, suggesting that ether amine is a more powerful collector for quartz than hematite. The negative zeta potential moduli of both minerals (quartz and hematite) compared to the values without reagents ( Figures 5a I and 5b I ) drop after conditioning with starch ( Figures 5a III and 5b III ).
SF flotation machine is used to separate nonferrous metal, ferrous metals, precious metals, nonmetal mineral and chemical raw materials, recycling useful mineral. The equipment has the following characteristics: breathe in large quantity, low power
The purity of hematite and quartz was above 98%, and the purity of chlorite was more than 90%, which were proved by the Xray Diffraction (XRD) method and multielement chemical analysis.
Flotation recovery of narrow size hematite (53×20 µm) particles as a function of pH is given in Figure 10. More than 77% hematite can be recovered in the flotation concentrate around pH 3. Further, flotation recovery decreases with an increase in pH.
Calculations of EDLVO theory and SEM indicate that some part of the fine grade siderite cover on the surface of hematite after the addition of coarse hematite, as a result, the apparent grain size of fine siderite as well as the possibility of adhesion between fine siderite and bubble are incresed, what's more, the environment of flotation is optimized as well.
the most popular flotation route in iron ore industry, the direct flotation of iron ox ides still appears desirable for some low grade iron ores that contain a vast amount of quartz. For example, at Republic Mine, Michigan,, a hematite ore is upgraded from % Fe to % Fe with a Fe recovery of % using the direct flotation route.
