|Title:||A METHOD AND PROCESS OF RECOVERING METAL VALUES FROM WASTE MONOLITHIC CERAMIC CAPACITORS|
The present invention relates to the recycling process of electronic waste resources to recover metals of value. More particularly, it relates to eco-friendly yet efficient hydrometallurgical processes to recover metal values from waste monolithic ceramic capacitors. In the proposed method, the source material such as mother boards having MLCC is pulverized using a ball mill to dislodge various components such as monolithic ceramic capacitors (MLCC) to form a powdery mixture of components. The mixture of components is then sieved. The MLCC powder of particular size range is then subjected to hydrometallurgical process. The process then transfers the precious metals into solution by leaching process followed by selective precipitation, purification, cementation and final recovery of metals.
