1. Introduction. Lead smelting slag (LSS) usually contains high content of heavy metals (HMs) such as lead (Pb), zinc (Zn), copper (Cu), cadmium (Cd), and arsenic (As) (Liu et al., 2018).However, its complex mineral composition and distribution characteristics make the utilization efficiency of resources low at present, and disposal is …

The Cu–Pb–As–Zn mineralization of Cap Garonne (Le Pradet, Provence, France; Fig. 1) is located in Triassic siliciclastic rocks, a few meters above the contact between Paleozoic and Mesozoic rocks (Fig. 2). It is the only known Cu–Pb–As–Zn association of Provence and surrounding areas, covering only a few hectares.

Furthermore, as shown in Fig. 1 b-c, the ball milling duration and the added content of P could significantly promote the biochar adsorption of Cd and Pb. A ball-milling duration of 12 h with 5% added P (BPBC700) resulted in maximum adsorption capacities for Cd and Pb, among which Pb adsorption was more efficient.

The results also show that Cu, Zn, Cd and Pb can be removed from the fly ash with high efficiency using hydrochloric acid leaching, which is beneficial since these metals are potentially toxic. The nitric acid systems shows less efficient leaching of Cu and Zn as well as poor leaching efficiency of Pb; only 9% could be removed at pH 2.

The profiles for the Pb phases are shown in Fig. 7. Exchangeable Pb, Pb1, shows a different pattern to Cu and Zn, with all samples containing lower concentrations than for these two metals (<0.5 ppm). Pb1 was only detected in two Rumney Formation samples, including the concretionary sand horizon, but was present in most of the …
