Chapter 2. Background UPSpace Home

Table 2.6 shows that zinc ethyl xanthate is more soluble than lead and copper ethyl xanthate. This implies that when copper, lead and zinc minerals are present in one system, the flotation of copper and lead minerals with xanthate will be more favourable than that of zinc mineral. Moreover, it is believed that the adsorption of xanthate on the
