THE USE OF COLUMN FLOTATION FOR THE RECOVERY OF ULTRA .flotation became the main type of flotation for water treatment appliions. These substitutions were the result of the absence of effective and reliable air spargers for fine bubble generation and by the lack of automatic control systems on the early columns. During this period, both the poor flotation selectivity and entrainment of slimes characteristic of impellertype cells was offset by ...
Flotation stabilization and optimizationThe control of flotation plants can be achieved by controlling aeration rate, reagent addition or froth depth. However, these control actions are effective over different time scales. Reagent addition is slower in its effect as some conditioning time is required. Also since reagents are typically introduced at the head of the circuit and at intermediate points within the banks, it requires ...

Process Control in Flotation PlantsProcess Control in Flotation Plants M. R. JAKHU Hindustan Zinc Limited, Udaipur ABSTRACT The processing of ores often entails use of unit operations such as grinding and flotation. Typical production requirements in mineral processing plants include the maximisation of throughput, maintenance of desired product quality and reduction of operating costs. For optimising plant performance ...
Modeling and Control of Lime Addition in a Flotation ProcessFlotation is an important and versatile mineral processing technique that is used to separate hydrophobic materials from hydrophilic. This technique makes it pos sible to mine complex ores that otherwise would have been regarded as uneconomic and nonbeneficial. In this case flotation is used to separate copper from the unwanted gangue. The addition of lime is used to control the pH level ...

Model Predictive Control of SAG Mills and Flotation Circuitscontrols downwards; so without the advanced regulatory control layer, the comprehensive plant automation strategy cannot be properly built. In this paper, an industrially proven adaptive modelbased predictive control strategy is reviewed and appliions to SAG mills and flotation cells are presented. P124 09/03 3 of 12
Model for the Design and Control of Flotation Plantsdesign and control of operating plants is w~U established, and much useful progress has been made. The analogy between the flotation process and a chemical reaction. which until fa irly recently was explored extensively as a possibl() mechanism for a viable model. is disappointingly weak because of the significant differences between individuaJ particles. However. usable mathematical models ...

MODEL BASED PREDICTIVE CONTROL OF A ROUGHER FLOTATION ...control strategies [3]. Flotation can be described with different diffi culty levels. Some works consider only a hydraulic model for evaluating regulatory control strategies [11], [13], [18]. Other works incorporate mineral recovery using mass balance equations that may consider pulp and froth phases, or a single mixture. If only one phase is considered, the mathematical complexity is ...
