THE ROLE OF ORE PROPERTIES IN THICKENING PROCESS

Mineral processing techniques are performed in environments which contain a significant amount of water, and in many cases, the most of water is removed with tailings. Therefore, it is necessary to use dewatering equipments such as thickeners in order to avoid environment contamination and water recycling (Burger et al. 1999).

10/10/2015  In the present study, an estimation model for yield stress of fresh uncemented thickened tailings (UTT) is proposed and verified based on rheological experimental results. As the model relates to the true solid density, bulk density, and solid concentration (C) of tailings, it is referred to as the TBC model. The change trend of yield stress with the variation of TBC properties is expressed by the first derivative of the TBC model.

Measuring Settling Rates and Calculating Thickener Capacity

03/03/2016  In the operation of continuous thickeners, the feed of the thin pulp at the center of the tank, the overflow of clear liquid at the periphery of the tank, and the discharge of the thickened pulp at the bottom, are generally continuous. In a continuous thickener, the four zones previously described in discussing intermittent settling are generally present as shown in Fig. 2. At the top there is a zone of

Mineral processing models have been discussed for many years but it was not until digital computers became available about 1960 that serious attempts at circuit simulation could be carried out. Even then the work was primarily academic until PCs could be used by engineers in plants and design offices in the mid-1980s. Since then simulation has moved quickly and it is now at the point that most ...
