The flotation recovery of sphalerite depends on the inorganic reagents concentrations in liquid phase suspension and pH. This paper presents results studies interactions iron (II) containing ions with surface water solutions at different pH levels. thermodynamic electrochemical were carried out to analyze possible sulfate a environment relate them potassium butyl xanthate sodium dibutyl dithiop...

Abstract Silver bismuth sulfide (AgBiS 2 ) is showing impressive thermoelectric and photovoltaic properties has a high potential to replace toxic cadmium or lead containing semiconductors in many applications. Herein, we report on synthesis route for AgBiS nanocrystals applying metal xanthates as precursors. could not be used so far solution‐based syntheses Ag‐containing they are typically inso...

In this study, the synthesis of porous beads from corn stalks was carried out. The cellulose extracted converted into xanthate and combined with alginate to form alginate-cellulose by ionic gelation method. This study attempted use sodium chloride (NaCl) as a porogen zinc acetate crosslinker. Beads were characterized determine porosity, swelling properties, functional groups using Fourier Trans...

A modular approach to substituted cyclobutylboronic esters is described. It proceeds by successive intermolecular radical additions of xanthates pinacolato 1-cyclobutenylboronate and bicyclo[1.1.0]but-1-ylboronate. Success hinges on tuning the stability α-boryl exploiting stabilizing influence trivalent boronic ester slightly destabilizing cyclobutane, which increases σ-character radical. Reduc...
