Craig âˆ— âˆ—Department of Electrical, Electronic, and Computer Engineering, University of Pretoria, Pretoria, South Africa. âˆ—âˆ—Department of Chemical Engineering, Norwegian University of

geostatistical analysis of all the data that is available. Although this paper is principally concerned with the use of such an analysis for the design of the grinding circuit, a short description of the geostatistics is a prerequisite to the understanding of the whole geometallurgical approach (Amelunxen et al, 2001). The analysis requires the

The grinding circuit model discussed in a separate paper or Part A of this project was then used interactively with the flotation circuit model to recommend the best operating regime to maximise overall efficiency. For example, the balance between increased crushing and grinding costs versus higher copper recovery and final concentrate grade.

learned about work index analysis* to define overall grinding circuit efficiency. In rod milling, you can use work index analysis to relate design and operating variables to overall circuit efficiency. However, you cannot use work index analysis for the same purpose on ball mill circuits because of the complex interactions between grinding and

A problem for solving mass balances in mineral processing plants is the calculation of circulating load in closed circuits. A family of possible methods for the resolution of these calculations is the iterative method, consisting of a finite loop where in each iteration the initial solution is refined in order to approach the exact solution.

Table of ContentsCase 1Case 2General NotesConclusions A Knowledge of the amount of time the material spends in a continuous mill in a closed-grinding-circuit is essential for circuit performance analysis and scale-up design. A convenient method for acquiring this information involves the use of tracers in residence-time-distribution (RTD

Advanced Grinding Circuit Control Using Online Analyzer Systems. Grinding circuit efficiency is pivotal to the performance of ore beneficiation. However, establishing stable operating conditions to maximize throughput, energy efficiency and ensure optimal particle size is a challenging task for any grinding circuit.

SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a

The data acquisition and modeling efforts are described first, followed by discussion of some of the simulation results. Observations pertinent to steady-state operation are presented followed by a description of the application of a dynamic model of the grinding circuit for synthesis and evaluation of grinding-circuit control.
