Mineral Extraction Processes
ATM Promining provides mineral processing solutions with what we and our esteemed client refer to
as the 'Triple E Two C' approach. 3E2C provides users with highly advanced and efficient mineral extraction systems that do not harm the environment not the operator and are most costs efficient at the same time. The energy costs are significantly decreased by sequential planning of processing steps and proper contextualization.

The initial material feed is drastically reduced through the means of pre-concentration as well as optimal utilization of both gravity based separation and (ultra) flotation. The result is a highly enriched concentrate which requires less energy while achieving outstanding recovery of targeted minerals. .
The effect of such ATM Promining systems is a operational result way beyond average.

Green Mining / Pro EnvironmentAll mining has an impact on nature as we retrieve valuables from it. That alone is not problematic and can be done in a balanced way. Yet this balance requires professional miners to make sure that the mining site is not contaminated and can be properly rehabilitated during and at the end of the mine life cycle.
The following principles apply to achieve this:
|
|
- using appropriate chemical agents with more optimal characteristics, if possible completely non hazardous
- if potentially hazardous chemicals are used proper tailing treatment needs to be ensured
- professional optimization of the processing set up in regards to environmental issues
In many instances processing can be achieved without the use of any chemicals. In other instances the processing can be done with non hazardous chemicals and proper tailing treatment that achieves zero contamination of the mining site.

Energy Optimized ProcessingIf the power consumption of the processing plant is not optimized operational costs may reach a level that endangers economical feasibility of the project in general. The optimization therefore is of high importance and must be addresses professional.
The energy optimization is divided into 3 main segments: |
Structural Energy Optimization
Comprises the decrease of energy consumption on a structural level. The sequences of processing steps for instance can greatly improve energy consumption. The reduction of material fed into the later processing steps requiring heat for instance is a very common example. That means that energy consumption can be optimized by structuring the processing cycles in a certain way.
Logistical Energy Optimization
This comprises the costs related to energy logistics and its possible optimization. Logistical ways can be kept as short as possible and storage facilities can reduce the logistical costs and optimize capacities transported by a single logistical cycle for instance.
Contextual Technological Energy Optimization
This segment is evaluating which means of power supply and generation are available for a project or location. If hydro power sources are an option and cut out expensive costs for fuel logistics for instance, optimization can be achieved. Parts of the facility might run on solar power rather then generators. There is a large variety of possible technological options allowing to customized the power supply to your particular project.

Mineral Processing EfficiencyEfficiency in mining and mineral extraction processes comprises many segments including: energy consumption, cost-efficiency, time efficiency and the recovery efficiency (recovery rate).
Energy and cost efficiency are elaborated on separately. What is meant by efficiency here focuses on the recovery rate and time as subjects of efficiency. |

Traditional placer Gold facilities in Indonesia rarely achieve recovery rates over 40%. Often the processing efficiency is around 15% only as they are not capable of extracting fine Gold for instance.
"A recovery efficiency of 88-98% must be the norm. That means the proper efficiency is 2-4 times higher than what is achieved by traditional means throughout Southeast Asia.
The efficiency of traditional systems in Southeast Asia used on refractory minerals is even lower and oftentimes zero. That is why miners here are often confused when they compare the reported total content of target minerals which can be very high and actual output, which oftentimes is zero. That usually means they do not understand how their minerals liberate and hence did not prepare accordingly and cannot extract it at all. This lack of awareness and preparation can be extremely expensive.
The willingness to consider "details" usually only appears after the fact once losses occurred. That must be prevented by proper preparation.

Know your ContextContext is a very important factor in mineral processing.
A solution that might apply to one project might be inappropriate for a project at a different location. The context is decisive and regulates the projects operational framework. Context interconnects with all other project segments. The context must be kept in sight and thoroughly considered prior to any operations. When we use the context separately we focus on the the financial, technological, social and geological context of the project as these play the major role in engineering and operational planning. Legal context is handled by legal counsels and have less actual cross section with engineering and operations itself.

Lower Costs - Better Performance
Lowering costs while improving performance and efficiency is the cornerstone of economic optimization. In mineral processing slight differences in recovery rate can constitute the difference between loss and profit. The more efficient the system and the lower the costs the less susceptible the project becomes to mineral content fluctuations.
As a consequences the Cost - Efficiency Ratio is crucial to the project especially where mineral content is near defined cut off grades. In locations with high grade deposits the difference made by optimized Cost - Efficiency Ratios is of less critical importance to the general feasibility yet directly reflected in profits.
