Abstract

The beneficiation plants generally process the production wastewater of the whole plant through natural concentration and clarification, and then feedback to each working procedure through the circulation pump house. This part of water referred is called circulating water in beneficiation plants. However, the circulating water in some beneficiation plants contains an excess suspended solids, which fail to meet the process demand of mineral separation [1-4]. Thus, it is necessary to conduct further treatment on the circulating water to increase water quality. The suspended solid in the circulating water is fine-grained, and difficult to precipitate due to separate particles is found uneasy to collide and forming flocs. The current investigation proposed a new type of deep clarification device to remove suspension solids, which was mainly composed of a hydraulic circulation chamber and a sludging and settling chamber. The schematic diagram of the device is shown in Figure 1. The hydraulic circulation chamber is mainly based on the principle of finite space jet flow [5]. As shown in Figure 1, the hydraulic chamber is mainly implemented on the basis of the principle of limited space jet sludge circumfluence to achieve improved suspended particles collide.
