Silver from spent fixing solutions offers a challenge to recover consistently the maximum possible grams of silver per square metre, resulting in a high financial return. It also helps in keeping a clean environment, whilst assisting in the maintenance of silver stocks. The benefits of control in management of silver recovery have been demonstrated using the high current density electrolytic method. While this system is expensive, the high prices paid for silver very quickly repay the initial cost. Thereafter with the exception of a small collection charge the return is considerable.
从用过的定影液中回收银面临着一项挑战，即要始终如一地每平方米回收尽可能多的银克数，从而带来高额的经济回报。这也有助于保持环境清洁，同时有助于维持银储备。采用高电流密度电解法已证明了在银回收管理中进行控制的好处。虽然该系统成本高昂，但银的高价能很快收回初始成本。此后，除了一小笔收集费用外，回报相当可观。
