Method for recovering aluminum compounds and MMA from waste artificial marble via acid treatment

Recovery of aluminum and MMA from waste artificial marble using acid treatment and solid-liquid separation

This technology involves turning waste artificial marble powder into a slurry and reacting it with an acid compound to extract aluminum components, followed by solid-liquid separation to isolate and recover aluminum compounds and PMMA.

Conventional recovery methods rely on thermal decomposition, which is energy-intensive and makes it difficult to efficiently separate and recover aluminum and MMA from waste artificial marble.

By recovering resources through acid treatment and solid-liquid separation without the need for thermal decomposition, this technology can be applied to waste recycling processes to recover aluminum compounds and MMA with minimal energy consumption.

Key Features:

• A pretreatment process that selects and prepares powder with a uniform particle size for recycling waste artificial marble
• A slurrying process that mixes water with the selected waste artificial marble powder to ensure fluidity
• An aluminum compound reaction process that mixes an acid compound into the slurry and heats it to react the aluminum components with the acid
• A solid-liquid separation process that uses a separator to isolate the aluminum compounds from the solid PMMA
