溜槽是一种最简单的沙金选矿设备，结构简单，无需动力，对工作场地无特殊要求，出沙量极大，但回收率较低，操作比较繁琐，自动化程度低，一般用于含金量低于0.5g，处理量大于3000方/天的沙金洗选厂中。溜槽的回收率较低，且需频繁的清理过程。跳汰机是常见的沙金选矿设备之一，在沙金选矿设备中跳汰机的回收率最好，及时对于较难回收的片状金和枝叶状金等不规则的金的回收也可取得较好的效果。大型采金船和选金厂均采用跳汰机作为最基本的沙金设备。跳汰机的出沙量不如溜槽，要求处理量较大的选金厂多采用溜槽与跳汰机配合使用，回收率可达到令人满意的程度。
Chute is one of the most simple gold mineral processing equipment, has the advantages of simple structure, no power, no special requirements on the work site, the sand volume is great, but the recovery rate is low, complex operation, low degree of automation, for gold content less than 0.5g, with weight greater than 3000 M3 / day in alluvial gold washing plant. The recovery rate is low, and need frequent cleaning process. The jig is one of the common gold mineral processing equipment, recycling jig in gold mineral processing equipment in the best rate for the more difficult, timely recovery of gold and gold leaf shaped lamellar irregular gold recovery can also be achieved good results. The large gold mining ship and gold with jig as the basic equipment of alluvial gold. The jig of the sand volume as the chute, gold processing requirements of large amount of the chute and the jig with the use, recovery rate can reach the satisfactory degree.
