2005-7-15Wood shaving fly ash was used as an alternative adsorbent for gold preconcentration from gold slag. The maximum gold adsorption capacity of wood shaving fly ash washed with tap water (WSFW) at 20, 30, 40, and 60 C was 8.68, 7.79, 7.44, and 7.25 mg Au /g adsorbent, respectively, while of activated carbon it was 76.78, 60.95, 56.13, and 51.90 mg Au /g
The tailings dry discharge is a new tailings processing process gradually emerging at home and abroad, that is, after the tailings slurry is concentrated in multiple stages, and then processed by efficient dewatering equipment such as dewatering vibrating screen to form slag with small water content, easy to precipitate, solidify and be stacked.

2020-8-17Mount Isa Mines operates two separate mining and processing streams, copper and zinc-lead-silver, near Mount Isa, Queensland, Australia. Its copper operations include two underground copper mines, Enterprise and X41, with ore mining capacity of 6.2 million tonnes per annum (Mtpa), a concentrator with 7Mtpa capacity, a copper smelter, and support services.
Cupellation is simple weigh the solid pieces of low grade gold, burn the crap out of it until you get no more slag and it becomes a nice bright yellow bead, and then you weigh it after it cools. My solid low grade gold parts with garbage attached went from 180 grains to 75.9 grains of high grade gold with no garbage attached.
Treatment of copper–gold concentrates using hydrometallurgical methods is beginning to make inroads into the traditional field of smelting in selected circumstances. A range of low temperature and atmospheric processes all the way to high temperature and pressure processes have been developed in the sulfate and chloride systems to treat these
The specification of Synthetic Slag varies plant to plant due to the difference in manufacturing factors,hence making Synthetic slag is a tailor made product suitable to individual specification and use .However We manufacture different slag based on Customer's specifications Requirements Product Specification CaO(%) 25.50 MgO (%) 03-06

Main smelting products: lead-bismuth alloy, reducing slag, copper dross, arsenic-antimony dross and smoking dust. The reducing slag contains gold of 0.95 g/t and silver of 80 g/t, with a unit consumption of natural gas of 80 Nm 3 /t slag. The resultant lead-bismuth alloy contains more than 90.94% of sum of Pb and Bi.
2018-8-5treatment and a resulting wastewater could have high metal concentrations. Process bleed streams may contain antimony, arsenic or mercury. Large quantities of water are used for slag granulation, but the majority should be recycled. Solid wastes and sludges The smelter contributes a slag that is a dense silicate.

2021-2-12The precious metals such as gold and silver are separated; the tailings after sorting are simply spread and dried to prepare a recycled product. Major equipment of power plant slag. The main equipment for the wet treatment process of domestic waste incinerator slag includes cross-belt magnetic separator, hammer crusher, drum screen, wet magnetic
thickness of gold contacts halved from ca. 1.0 mm in devices manufactured in the 1980s to 0.6–0.3 mm for those made in the 2000's.11 Pre-separation treatment of e-waste The processing of e-waste typically begins with a manually intensive dismantling phase, during which circuit-board components and the lithium battery are removed for recycling

Submerge the unrefined gold in a mixture of nitric and hydrochloric acids. This method will dissolve the ore and separate the gold from the impurities, which can later be washed away. The remaining substances will be just water and gold, the latter having a purity level of more than 99.99 percent. Dry this residue until only gold powder remains.
2021-2-3Sealed Gold Capsules. The effect of temperature and initial acid acetic concentration on the hydrothermal oxidation of steel slag was first investigated by conducting a set of experiments in 2-cm long gold-capsules. Around 80 mg of steel slag and 80 mg of de-ionized water are loaded in a gold tube (outer diameter of 4.4 mm).
