溜槽选矿是利用沿斜面流动的水流进行选矿的方法。矿浆给人溜槽后,不同密度的矿粒的松散分层与分离过程是在水流的作用力、矿粒重力(或离心力)、矿粒与槽底的摩擦力等的联合作用下进行的。分层结果是密度大的矿粒集中在下层,以较低的速度沿槽底向前移动,然后排出槽外或沉积在槽底上成为精矿;密度小的矿粒集中在上层,以较大的速度被水流带走,成为尾矿。因此,不同性质的矿粒,在槽内得以按密度选分,但矿粒的粒度和形状将影响分选的精确性。
溜槽的种类较多,根据处理矿石的粒度可以分为矿砂(大于74微米)溜槽及矿泥(小于74微米)溜槽两大类。
A method for processing the chute flow along the slope of the. Pulp to the chute and different density of mineral particles loose stratification and separation process is carried out under the combined action of the force of the water, mineral particles gravity (or centrifugal force), mineral particles and groove bottom friction. Hierarchical result is density of ore grain in the lower layer, with lower speed along the bottom of the tank and move forward, and then discharged the slot or deposited in the groove on the bottom of a concentrate; density of small mineral particles concentrated in the upper, with great speed is carried by a stream of water, become tailings. Therefore, the different properties of the ore particles, in the slot to be chosen by density, but the size and shape of the ore particle size will affect the accuracy of sorting.

Chute of many kinds, according to the size of ore processing can be divided into ore (more than 74 microns) chute and slime (less than 74 microns) chute. The commonly used chute is shown in table 3-4.
