It is recycled. Copper, like other metals it melted back down for farther use in other products and structures.
Given 1 gm of MCl2 fors 1.286g of AgClmolar mass of AgCl is 143.5 g 1.286g of AgCl contains 1.286/143.5 mols of AgCl =0.0089616 molseach mol of MCl2 release two Cl- ionshence number of mols MCl2 given(1gm) is 0.0089616 /2=0.0044808 mols hnce one mol of MCl2 weighs 1/0.0044808= 223.17g
