recommendations! Published in 2021 at "Applied Surface Science"

DOI: 10.1016/j.apsusc.2021.151055

Abstract: Abstract A novel surfactant trimethylacetyl thiobenzamide (TTBA) was synthesized and first conducted as flotation separation collector for galena and sphalerite. The flotation performance of TTBA and traditional collector sodium isobutyl xanthate (SIBX) was investigated by… read more here.
