The order of metal uptake efficiency for these zeolites was determined to be Pb > Cu > Zn > Ni. These results indicate that zeolite composites synthesized from natural calcite-bearing kaolin materials could represent effective and low-cost adsorbents for heavy metal removal using water treatment devices in regions of water shortage.

calcites contain significant Mg, Mn, Fe, Ni, Cu, Zn, and Pb, yet very little Co, Rb, Sr, La, Ce, or U. Secondary calcium carbon - ates provide subseafloor reservoirs for some minor and trace elements. Replacement of aragonite by calcite should result in a release of Sr, Rb, and Zn to solution, and it provides a sink for Mg, Mn, Ni, Cu, Zn, and Pb.

The Effects of Milling and pH on Co, Ni, Zn and Cu

1.5. Additional milling to decrease particle size from the initial d80 < 150 m had a major positive effect on cobalt- and nickel-leaching yields, proposing that at least d80 < 28 m should be targeted. The best leaching yields for the main economic elements, cobalt and nickel, were 98% and 94%, respectively, reached with d80 < 19 m at pH 1.3.

program. Data from the mill in 2013 showed that the Zn recovery to the Cu rougher circuit was 3.02% whereas that from the flotation tests was on the order of 10%. This big disparity in Zn recovery to the Cu concentrates suggests that there is some surface chemical control operating in the mill that was not apparent in the previous testing.
