目前，我国许多砂金矿山普遍采用大型选金溜槽进行粗选，其粗选矿可单独采用淘金盘或小型选金溜槽加淘金盘进行精选。选金溜槽结构简单，不需动力，处理量大，选别粒级宽，富集比大，制造容易，使和和维修都很方便。但清溜劳动强度大，对细粒金选别效果差适用于自然金粒度较大，小规模生产时做为粗选设备。国外大都用圆锥选矿机、螺旋选矿机和罗斯溜槽等设备取代大型选金溜槽。这些设备除了具有选金溜槽不消耗动力、处理量大等优点外，还有降低劳动强度、强化细粒级回收和易于搬迁等优点。
At present, many gold mines in China is widely used in large-scale gold chute roughing, the coarse dressing can be individually by using gold disc or small gold chute with gold disc were selected. Choose gold chute has the advantages of simple structure, no need of power, large capacity, choose different grain width, large concentration ratio, easy fabrication, and maintenance are very convenient. However, the labor intensity is large, and the selection of fine particles is not suitable for the large grain size of natural gold, and the small scale production is the coarse equipment. At home and abroad are replaced by large gold chute with cone concentrator, spiral chute and Ross etc.. These devices in addition to choose gold chute and power is not consumed, processing advantages of large quantity of outside, and a decrease in labor intensity, enhanced fine-grained recovery and easy to relocation and other advantages.
