近年来 ,在冶金学家的语汇中很少出现“槽浸”这类字眼。而早在 1888年 ,利用氰化物浸出金的方法就已盛极一时。自那以后的许多年内 ,对工艺进行了改进并研制了新设备 ,旨在提高槽浸 (又称砂浸 )的生产能力 ,以利于贵金属的回收。多年来 ,由于效率和经济性方面的原因 ,槽浸已被
In recent years, few words such as “trough dip” appear in the vocabulary of metallurgists. As early as 1888, the use of cyanide gold leaching method has been very moment. For many years since then, the process has been refined and new equipment developed to increase the capacity of tank dipping (also known as sandblasting) to facilitate the recovery of precious metals. For many years, trough leaching has been done due to its efficiency and economy
