Determination of gold and silver in geological samples by focused
Focused infrared radiation-based digestions, for the determination of gold and silver, can be achieved in a timeframe as short as 10–15 min, making it an attractive candidate technology for the mining industry, where very large numbers of samples are analyzed on a daily basis. An investigation was carried out into gold and silver The apatite ore is a host to heavy metals impurities such as cadmium (Cd), lead (Pb), arsenic (As), mercury (Hg) and nickel (Ni) (Dawson et al. 1996;Mar and Okazaki 2012; Meck et al. 2011Sketch Geology map of the Dorowa Carbonatite after [21].

Separation of H3PO4 from HCl-wet-processing phosphate rocks
Using HCl to replace H 2 SO 4, phosphate rock is decomposed according to the following reaction: C a 5 F P O 4 3 + 10 H C l → 3 H 3 P O 4 + 5 C a C l 2 + H F. Hydrochloric acid route not only avoids the generation of phosphogypsum, but also improve the profits of the process. Due to the excellent reactivity of HCl, even low-grade Life cycle assessment (LCA) tools can be used for the environmental assessment of municipal solid waste management (MSWM) systems. The present study aims to evaluate the impact of an MSWM system in Riyadh, Saudi Arabia, under three different scenarios based on the Strategy for 2045 of Riyadh.
