The present disclosure provides a full-reflection display substrate, a manufacturing method thereof and a full-reflection display device. The full-reflection display substrate includes: a base substrate, the base substrate including a display region and a non-display region; a signal line arranged in the display region; a bonding pin arranged in the non-display region, coupled to the signal line and bonded to a driving circuitry; a reflection layer arranged in the display region; and an etch stop pattern arranged at a same layer and made of a same material as the reflection layer, arranged in the non-display region, and at least covering a side surface of the bonding pin.

A method for recovering materials from waste or scraps through an improved microwave carbothermal process involves combining reagents of a carbothermal reaction to form a mixture to be subjected to heat treatment, the reagents including a component in which an element to be recovered is contained and a carbon-containing component, the component being contained within a waste material, placing the mixture in a crucible, placing the crucible in a refractory chamber having a side wall, a surface of the side wall being covered by a layer of microwave-sensitive material, and inserting the refractory chamber into a microwave oven. The carbothermal reaction is obtained in less time and with lower electricity consumption compared to typical carbothermal reactions.
