Froth flotation is an efficient and economic beneficiation strategy to obtain smithsonite from raw ore [6].Nevertheless, the one of the dominant surface properties of smithsonite is strong hydrophilicity [7], so it is much harder than the flotation of zinc sulfide from sulfide deposits.For carbonate minerals, fatty acids exhibit superior collecting ability [8].

Depth profiling was achieved with Ar ion etching at a current of 10 nA, beam energy of 1000 eV, and a sputtering area of 0.01 × 0.01 cm 2. The surface morphology and energy spectrum of smithsonite were characterized using a high-resolution FESEM (CIQTEK, SEM 5000, Hefei, China) with an EDS. (OXFORD Xplore, Oxford, UK).

Smithsonite, the most common zinc oxide minerals, has become a good alternative for zinc extraction. Flotation is the most widely used approach to separating smithsonite from gangue minerals, because of the its low cost, high selectivity and easy operation [8]. Calcite is one of the most common gangue minerals that coexists with smithsonite [9].

A wonderful specimen of the classic Smithsonite from the Monte Cristo Mine in Rush Creek, Arkansas. The piece has a good coverage of rich yellow-orange aggregates of eye-catching Smithsonite (which get their color from cadmium content) which are coating "curved" rhombs of Dolomite on matrix. There is a little damage, but it's in good shape overall.
