MINERAL PROCESSING PLANTS
Simulation starts with the definition of the
flowsheet which is drawn initially on the monitor using a specialized
The graphic editor has an extensive array of icons representing all the
mineral processing unit operations encountered in practice.
The editor also allows for quick modification of the flowsheet structure and
replacement of existing units.
Data required to simulate processing plants
describe the characteristics of the material treated, the production rates
targeted, and the details of the unit operations included in the flowsheet.
The processing units are described by their physical characteristics and the
parameters of the mathematical models that describe the operation of the
MODSIM™ is based on the population
balance method and is therefore capable of accounting accurately for
variations in particle size and mineral liberation characteristics together
with other critical properties such as density, mineralogical texture,
elemental composition, magnetic susceptibility, energy content, etc. Data structures
incorporate mineral and coal processing flowsheets.
MODSIM™ simulates integrated flowsheets
that can include:
(jaw, giratory and cone crushers, high
(AG, SAG, Rod and Ball mills)
- classification (screens and hydrocyclones)
separation (jigs, tables, cones, sluices, dense medium vessels and
cyclones, water only cyclones)
separation (dry and wet drum separators and wet high intensity
- solid liquid separation
(thickeners, dewatering screens and filters).
A wide array of models for the unit
operations is supplied. In most cases alternative models are available so
that the user can investigate the differences between various models of the same
Most of the significant models available from the scientific literature are
included. Each model comes with a set of realistic default parameters.
User-specified models for any unit can be incorporated easily. Model
selection is fully interactive so models can be changed with a simple mouse
Graphical, tabular and text outputs display simulation results quickly and
clearly. All output can be copied and pasted on most word processors for
convenient and effective report production.
Graphics can be exported as Encapsulated PostScript (.EPS) or Windows
