Gold is used in various fields and a rare resource nature. Recovery of gold from domestic wastes desired Japan. Bamboo an abundant biomass Japan, the promotion its utilization desired. In our previous studies, sulfur-impregnated carbonaceous adsorbent with high heavy metal removal has been prepared resources using sulfur affinity for metals. this study, bamboo was powder by pyrolyzing at 800°C ...
Environmental desulfurization is gaining attention as an efficient approach to manage sulfidic mine tailings by separating sulfide minerals from tailings. While extensive research has been done reuse desulfurized in site reclamation, the responsible management or potential of valorization concentrates did not receive much attention. The objective this study was evaluate recover Au originating a...
The South African gold mining industry has a legacy of abundant tailings dams, which have attracted the attention investors because their potential as cheaper secondary resource. In this we investigate study recovery from refractory calcine dam. Bulk mineralogy indicated silicates and iron oxides to be most phases. Scanning Electron Microscopy (SEM) showed exist in submicrometre micrometre size...
Plasma membrane, coated pits, endosomes, and lysosomes were isolated from a mouse T lymphoma cell line using a density shift protocol in which these compartments were selectively loaded with gold conjugates. The plasma membrane was prepared after selective labeling for 1 h at 2 degrees C with gold-ricin and gave a yield of 40% according to enzymatic and antigenic markers. Endosomes were obtaine...
Gold recovery using environmentally benign chemistry is imperative from an environmental perspective. Here we report the spontaneous assembly of a one-dimensional supramolecular complex with an extended {[K(OH₂)₆][AuBr₄](α-cyclodextrin)₂}n chain superstructure formed during the rapid co-precipitation of α-cyclodextrin and KAuBr₄ in water. This phase change is selective for this gold salt, even ...
