Turkish quartz mining company Mikroman Madden AS, founded in 1991, adopted sensor-based sorting technology for the first time in 2018 at its three processing plants. Thus, they installed three Tomara Pro Secondary Laser high capacity sorters and achieved their goal of improving product quality and increasing the capacity of these facilities.

At its plant in Kula, Manisa province, the company needs to make ore classification more accurate. To do this, they combined Tomara’s color and laser technologies with a dual purpose. On the one hand, maximizing recovery with the highest purity levels, to get the best results. On the other hand, creating a product of different qualities to meet the specific needs of different types of markets. Tomra’s solutions have consistently delivered the desired quality standard across all categories, while increasing productivity and reducing waste.
Our collaboration with Tomra and its color and laser sensor-based sorting technologies has significantly improved the quality and efficiency of our production, says Serhat Saran, Chairman of the Board of Directors and CEO of Microman. The company discovered the potential to expand its activities and enter new markets using these solutions: The use of sorting systems with laser and color sensors has enabled us to explore various sectors by modifying the quality and chemical composition of micronized and granular products. allowed to serve.
Microman Madden maximizes recovery with the highest purity levels.
Satisfied with the results obtained with Tomara’s PRO secondary color and laser sorters at the Kula plant with larger particle sizes, Microman asked Tomara for a solution to better process the material and add value.
At that time Microman was processing particles sizes up to 15 mm with a Pro Tertiary color sorter, and Tomara installed three other such sorters for finer particles: one with particle sizes from 2 to 4 mm and one with size from 4 mm. Two machines to classify for 10mm. In this way, color impurities can be removed from the quartz, which continues to be processed in a micronization plant in the same facilities. With these sorters, Microman has been able to diversify its product to provide different properties required by different sectors, as well as process smaller particle sizes.

On the other hand, the company also wanted higher purity levels to be achieved with laser technology in grain sizes of less than 20 mm. However, explains Ines Hartwig, director of product management at Tomara Mining at the time, the Pro Tertiary was only available with color technology. That is why we decided to start developing a new Tomara product on the pro tertiary platform, but with multi-channel laser technology. In addition, with this solution, white impurities such as shale, feldspar, slate and calcite can also be detected and graded to obtain the purest white quartz product of the best quality.
Thus Tomra developed the new PRO tertiary laser sorter and put it through an intensive testing program, in close cooperation with Microman, as Serhat Saran explains: We operate as Tomra’s research and development department is our own. was.

Ines Hartwig says: Once laser technology was applied to larger grain sizes, Microman was already able to see the advantages it brought compared to Tomra’s color sorters, it was clear that the company was looking forward to collaborating with us. was the perfect partner. Design and test this new product. They provided us with sterile and product reference samples that they hoped to classify into smaller particles and our engineering team developed the new machine with the help of Markus Dahler, manager of the Tomara Mining Test Center.
The Pro Tertiary Laser Sorter employs the same multi-channel laser technology as the Pro Secondary platform, but specializes in detecting and sorting materials of smaller sizes, from 6 to 32 mm. The distance between detection and ejection is minimized and the number of ejectors is increased to provide highly accurate, effective and efficient grading and high quality products.
Tomara Pro Tertiary Laser is a low-maintenance, simple and stable platform that has the advantage of being the only one in the market that offers the ability to customize laser wavelengths to suit specific applications.
The development was completed in a short time and the new PRO tertiary laser sorter was installed at the Kula plant to process grain sizes from 5 to 15 mm and 15 to 35 mm.
Two combined Pro tertiary color and laser sorters systematically remove up to 98% of impurities in small sizes from 5 to 35 mm. In addition, they provide significant savings in water, fuel and electricity in post-transformation operations.
With these investments, Microman has expanded its capability and product portfolio to serve a greater number of sectors: composite stone, glass, electronics, metallurgy, paint and ceramics, among others, and currently including the United States. Exports to 15 countries. , Spain, Italy and Israel.
Using Tomara technology gives us the confidence to deliver a high quality, consistent product with our customers, says Never Kuau, Project Manager, Microman.
With these investments, Microman has expanded its capability and product portfolio to serve a large number of industries.
Tomra offers us the ability to classify all kinds of sizes according to the color and chemical composition of the product. This has allowed us to become a leader in this field, and exports worldwide and Turkey accounts for 65% of domestic sales, concludes Serhat Saran.
The collaboration with Tomra has evolved in parallel with the pace of activities of Microman, with the addition of more color and laser sorters, now totaling 18 units spread over four floors.
Today, it has 10 Tomara graders at its Yava and Kula plants, one at its Karpuzlu mine in Aydin Province, and two graders at its new Catalca plant in Istanbul.
To support its continued growth, Microman invested in two new PRO tertiary laser sorters: one for the Kula plant and one for the Yava plant.
Their latest investments include two PRO tertiary color sorters and one PRO tertiary laser sorter which have already been delivered and will soon be installed at the Kula plant.
