TL;DR: In this article, a novel process of recovering from high tellurium-bearing materials by alkaline sulfide leaching followed sodium sulfite precipitation is developed, where the influences of Na 2 S concentration, leaching temperature, liquid to solid ratio and leaching time were studied during the leaching process.

TL;DR: In this paper, a novel process for recovery of tellurium (Te) from alkaline solution by cyclone electrowinning was proposed, which indicated that TeO32− ion was first reduced to Te(s), then to Te22− ion.

TL;DR: In this article, the rotational flow electrodeposition technology is used for the preparation of the tellurium powder for the first time, the flow velocity of the solution is increased with the help of the electrodepositions technology, the thickness of a diffusion layer is lowered, the limiting current density is increased, and the precipitation precipitation of the high current density under the highcurrent density is achieved, a process which is economical and environmentally friendly and is suitable for industrial production.
