DOI: 10.1016/j.seppur.2019.116408
Abstract: Abstract In this study, the separation of calcite and apatite was achieved by the depressant sodium pyrophosphate (SPP). Microflotation results showed that when using 20 mg/l sodium oleate (NaOL) as the collector, apatite could be significantly… read more here.

DOI: 10.2138/am-2024-9387
Abstract: Abstract Sodic volcano-plutonic terranes in the Archean can be well preserved, but why oxidized S-rich sodic magmas and porphyry-type Cu-Au deposits are so rare remains poorly understood. Here we addressed this issue by measuring the… read more here.
