Sphalerite: Mineral information, data and localities.

Sphalerite Group. Sphalerite, also known as blende or zinc blende, is the major ore of zinc. When pure (with little or no iron) it forms clear crystals with colours ranging from pale yellow (known as Cleiophane) to orange and red shades (known as Ruby Blende), but as iron content increases it forms dark, opaque metallic crystals (known as Marmatite).

MLAbased sphalerite flotation optimization: Twostage

a) Sphalerite flotation rate experiment. In generally, rougher plays a decisive role on the overall flotation process. To investigate roughing behaviors of the sphalerite, benchscale flotation tests were performed using an XFD machine which was equipped with a 1.5 L flotation cell.

It was found that the sphalerite showed a certain degree of natural floatability ground by the porcelain ball mill, while the sphalerite lost its natural floatability ground by the steel ball mill. Smithsonite can be directly recovered by the flotation process with advanced xanthate or collector of fatty acid, but the selectivity is very poor.
