溜槽选金是一种古老且迄今仍在使用的重选方法。溜槽选金的主要设备是溜槽。溜槽是一倾角为3°~4°(最大不超过14°~16°)的木制(或钢材)狭长斜槽。黄金行业可就地制造。分选原理是:矿浆从槽头给入溜槽后,在水流作用力、矿粒重力(或离心力)、矿粒与槽底间摩擦力等力的联合作用下,不同密度的矿粒松散分层和分离,密度大者在槽底成为精矿,密度小者成为尾矿。溜槽为间歇作业,当槽底精矿沉积到一定高度时,停止给矿,清出精矿。
溜槽分粗砂溜槽和矿泥溜槽,前者适于处理粗粒级的物料,后者适于处理细粒级物料。粗粒溜槽槽底装有铺物和挡板,
Gold chute is an old and is still used in gravity separation method. Chute is main equipment of gold chute. Chute is a slope of 3 degrees ~4 (maximum of not more than 14 DEG ~16 DEG) (wooden or steel) narrow chute. Gold industry can be made in situ. Separation principle is: the pulp is fed from the slotted chute, in the flow force, mineral particle gravity or centrifugal force) and mineral particles and between the bottom of the slot of the friction force under the action of combined, mineral particles of different density of loose stratification and separation, high density at the bottom of the groove become concentrate, small density into tailings. Chute for intermittent operation, when the bottom of ore deposition to a certain height, stop feeding, cleaning concentrate.

The chute consists of coarse sand and mud chute chute, the former is suitable for processing coarse material, which is suitable for processing fine materials. Coarse sluice trough bottom is provided with a shop and baffle,
