Are Your Process Variables Under Control?
A proper training program would include a description of the process, flowsheets, and
detailed descriptions of the principle of operation of key equipment items and process
Once the operators have a good grasp of the process and the particular control loop,
trainees would be taught to troubleshoot process variable problems logically, by
drawing on their knowledge of the process equipment, flows, and control methodology.
Maintenance Cost Control—Is Your System Active or Passive?
Although many mines and processing plants have sophisticated maintenance cost information
systems, cost control relies ultimately on management actions based on the information such systems
A systematic management approach to solving problems and implementing solutions
is the key to effective maintenance cost control.
Process Control Training—Simulators Are Only Half the Story
With reference to greenfield plant projects, using process simulators similar to the designed
plant Human Machine Interface (HMI) or Distributed Control System (DCS) has become
These simulators represent a "virtual plant" based on process modeling
of the circuit chemistry and thermodynamics, and on the physical nature of the plant, including
equipment, valves, piping, etc.
Total Quality Management—The Time Has Come for Metallurgical Plants
The principles of quality management are
well developed and, from a practical standpoint,
thoroughly implemented in the process industries
Although these principles are now applied
to the U.S. manufacturing industry, and as
a result, the steel industry, they have been largely
ignored in the non-ferrous and precious metals
Preparation of Effective Computer-Based Operator Training (CBT) Programs for Metallurgical Plants
Effective plant-specific computer-based training (CBT) used in a formal training program can
make the difference between a successful start-up and a failure.
Or, in the case of an existing plant,
it can make a huge difference in the effectiveness of operating results particularly if turnover of
experienced personnel is a factor.
So You Are Investing in a Mining Project—What Usually Goes Wrong
The geology report, feasibility study, and mine plan look great. Why do so many gold mine
start-ups fail to perform?
Most mining companies put a great deal of emphasis on the nature
of the reserve, the mine plan, the extraction process to be used, and the process plant design, obviously all very important.
Spare Parts Planning for New Metallurgical Plant Start-Ups—Why You Need a Spare Parts Inventory Model
Standard practice for newly constructed metallurgical plants is for equipment suppliers
to recommend sufficient spare parts for the first two years of plant operation.
However, this approach is inadequate, as it does not consider several factors.
Metallurgical Plant Commissioning—Are There Any Shortcuts?
During the final stages of metallurgical plant construction there is tremendous pressure
to commence production. More often than not, there will have been budget overruns
and schedule delays. Corporate management and investors are naturally anxious
to generate cash flow.
How Does Your Plant Measure Up? Develop a Productivity Profile to Find Out
How can the overall performance of your plant be determined? Most plants calculate
availability, or the percent of the time the plant or a particular circuit is operating, as
well as overall production and recovery. But, is this information enough? Does it provide
sufficient fine-grained information on where improvements can be made?
Metallurgical Process Plant Safety—An Integrated Approach
In many mine and plant operations, safety is looked upon as an extra layer of special
attention placed above the operations management layer. In this approach, safety
awareness and procedures are tacked onto the “normal” operations and maintenance
If You Are Planning on Developing a New Mining Project, You Need an Operations Readiness "Road Map"
A mining project’s bankable feasibility study identifies the deposit geology, drill results, statistical
analyses of the expected ore grade, basic mine plan and engineering, basic process
plant design, capital and operating cost estimates, and staffing ramp-up plan. What’s missing?
Most feasibility studies do not adequately identify those non-engineering or construction activities
necessary to successfully start up the mine and plant.
