Gold recovery (usually also called gold recovery) is the recovery of gold products or gold-containing articles, and the basic purpose of recovery is to realize or reuse. Gold recovery is different from general goods recovery. Whether it is the weighing of weight, the determination of color or the determination of price, it has formed a unique recovery system. Because gold is recycled, it is also called recycled gold regardless of brand, and the main price factor of recycling is gold content.
