Limestone separation from quartz

The Shanbaidu polymetallic deposit comprises genetically related but spatially separate iron and lead-zinc skam deposits in the contact zone of quartz-diorite and limestone. The ore minerals are mainly magnetite, hematite, galena and sphalerite. The ore bodies are found at depths of 5-40 m, and the surface of the area is covered by 5-15 m of transported exotic overburden. Thermally-released Hg, data from samples collected at depths of 30, 60 and 80 cm in the soil along a traverse crossing both ore deposits are shown in Fig. 13-9. In the samples from 60 and 80 cm, clear anomalies mark the positions of the mineralisation. In the samples from 30 cm, however, the background is... 

The diagram in Figure 9.1 summarizes the process for separating the montmorillonite clay from other nonclay minerals, such as quartz, gravel, limestone followed by...
