    • A precious metal recovery system utilizing an amalgamation process which results in substantially complete recovery both of the precious metal sought and of the mercury utilized in the process. Mercury has undesirable health and environmental characteristics and the system of the invention assures its substantial containment. In the operation of the system, ore is classified and sorted out into a plurality of bins or holds containing ore having a substantially uniform particle size. The ore is then delivered, bin by bin, beginning with the smallest particle size, to apparatus which assures substantially complete amalgamation of all of the precious metal present in the ore. Thereafter, a resulting slurry of water and tails is first removed from the amalgamation apparatus and any residual mercury removed before its return to the environment. At the end of a period of operation of the amalgamation apparatus, the mercury and precious metal amalgam mixture together with any residual tails are drawn off and subjected to three separation operations. First, the mercury and precious metal amalgam mixture is separated from any residual tails. Next, the mercury is separated from the precious metal amalgam. Finally, the mercury is removed from the amalgam thereby resulting in a reasonably pure form of the precious metal.
    • 一种利用合并工艺的贵金属回收系统,可以使所寻求的贵金属和该方法中所使用的汞达到完全回收。 汞具有不良的健康和环境特征,并且本发明的系统确保了其大量的遏制。 在该系统的操作中,将矿石分类并分选成含有具有基本上均匀的粒度的矿石的多个箱体或保持架。 然后将矿石以最小颗粒尺寸开始输送到确保矿石中存在的所有贵金属基本上完全合并的装置。 此后,首先从合并装置中取出所得到的水和尾部浆料,并在其返回环境之前除去任何残留的汞。 在合并装置的运行期结束时,将汞和贵金属汞齐混合物与任何残留尾料一起排出并进行三次分离操作。 首先,将汞和贵金属汞合金混合物与任何残留尾部分离。 接下来,汞与贵金属汞齐分离。 最后,从汞齐中除去汞,从而形成相当纯净的贵金属形式。

    • In a gravity flow amalgamator an elongated upright housing is provided with a removable bottom end tray containing a bath of mercury for collecting gold. A pair of partition walls extend inward and downwardly in parallel relation transversely of the housing to form a water channel downstream tortuous path characterized by return bends with each wall of the pair of walls respectively attached to the inner surface of the housing opposing side walls intermediate their height to define fluid compartments at opposite sides of the housing. The water channel discharges the water into one of the fluid compartments.
    • 在重力流动合并器中,细长的直立外壳设置有可移除的底端托盘,其包含用于收集金的汞浴。 一对分隔壁在壳体的横向上以平行关系向内和向下延伸,以形成下游曲折路径的水道,其特征在于:返回弯曲,该对壁的每个壁分别附接到壳体的内表面, 高度以在壳体的相对侧限定流体隔室。 水通道将水排放到一个流体隔室中。
