Copper, river, c.300 mi (480 km) long, rising in the Wrangell Mts., SE Alaska, and flowing S through the Chugach Mts. to the Gulf of Alaska. Copper deposits near the upper river, long mined by natives, attracted the attention of Russians and later Americans, but exploration was difficult because of the river's currents and the glaciers near its mouth.


• Indium is produced mainly as a byproduct of zinc, and to a lesser extent as a byproduct of copper, tin, and polymetallic deposits from mineral ores containing less than 100 parts per million (ppm) (or less than 0.01%) indium.3 We estimate that the indium content of zinc and other ores from which indium was recovered in 2013 was ~700 tonnes.

The precipitate is leached with NaOH solution to create crude indium hydroxide (In(OH)3), containing 20 % In, 6 % Zn, 1.5–3 % As, and 0.5–2 % Cd. The crude In(OH)3 is leached with dilute HCl. The In solution is purified by cementation of Cu and As with Fe, followed by cementation of Sn and Pb with In.

Flotation is used to recover most of the non-ferrous metals and associated rare and precious metals, such as gold, silver, rhenium and indium In the flotation process, the hydrophilic and hydrophobic differences of various minerals are enhanced by the selective adsorption of flotation reagents according to the physical and chemical properties ...


Flotation. Floatation is a process that when air is bubbled into liquid, suspended matters in the liquid then adhered to air bubbles and floated on the surface of the liquid as a foam. In 2018, studies have focused on flotation methods and the use of surfactants, but only a few on flotation in water treatment, which are summarized as follows.


In this paper, we report a new, simple method for the synthesis of CdS and ZnS nanoparticles (NPs) prepared in a basic aqueous medium using metal xanthate as the sulfur source. The structure, morphology, size distribution, optical band gap, and photocatalytic properties of the newly obtained nanomaterials were investigated by UV-Vis spectroscopy, X-ray diffraction, and transmission electron ...
