During the process of physical crushing, silicon particles adhered by slag adhesion will be produced, thereby making the separation of MGSRS and silicon incomplete and resulting in low recovery efficiency. ... As is commonly known, in the molten state, metal can separate from slag, such as copper slag [27], steel slag [28], etc., and settle to ...
Cooling and Crushing . The oxidized material called slag is poured off into large cast-iron trays and cooled. Once the cooling process is complete, the silicon metal is dumped into a truck to break it up for storage. Moreover, jaw or cone crushers are used to reduce the size of the metal based on customer specifications. Packaging
The silicon metal is cooled in large cast-iron trays that measure about 2.4 m across and 20 cm deep. After the cooling process is completed, manufacturers dump the metal from the mold into a truck to break it up in preparation for storage. Crushing Process. They measure the weight of the metal before they dump it into the storage pile.
