Modern production

Thanks to technological know-how and modern procedures, we bring first-class products to the market. When processing kaolin, we mainly use natural resources. We use water to perform the process of washing and dewatering. We achieve its high whiteness by magnetic separation. We further process fine-grained kaolin by thickening, pressing, drying and grinding.

Logistics and shipping

We supply most of the kaolin in the form of lumps. We transform them into powdered kaolin by grinding and drying. We ship unpackaged kaolin in batches of 20 to 50 tons on wagons and trucks. Part of it is supplied in big bags weighing from 500 to 1200 kg. For smaller consumers, we prepare kaolin in paper bags weighing 25 to 45 kg.

  • Expedition on pallets and wagons

Frequently Asked Questions

    How does mining take into account the environment and the landscape?
    The extraction of minerals undoubtedly means an intervention of the environment. In order to mitigate the impact, we assess the mining plan from several points of view, which are regulated by Act No. 100/2001 Coll. We evaluate the impact of mining on the population, air and climate, surface and groundwater, and soil. We are also concerned with the impact on fauna, flora and ecosystems, as well as public health, tangible assets and cultural monuments. Only after the assessment of all of these effects are measured, are the conditions under which mining can be carried out determined. Upon completion of this process (EIA), a mining plan is prepared, which is the basis for issuing a mining permit. If the mining company plans to remove agricultural land or forest land due to logging, it is necessary to prepare a Comprehensive Rehabilitation and Reclamation Plan. This approved plan ensures that the consequences of mining activities are eliminated.
    Wildlife and protected plants in the area
    Before the very beginning of mining, experts in the biological evaluation of the landscape assess what species of plants and animals live in the place. At the same time, they pay special attention to protected and endangered species in accordance with Implementing Decree No. 395/1992 Coll. to Act No. 114/1992 Coll. These protected plants and animals must be moved to alternative plantings and nesting sites before mining. Soil removal and tree felling are carried out outside the growing season and the nesting period of the birds. From the beginning of mining until the reclamation of the landscape, professional supervision according to Act No. 114/1992 Coll. oversees vegetation and flora and focuses mainly on specially protected species of plants and animals and the state of their habitats.
    How does society contribute to the subsequent protection of nature?
    After the end of mining, our work does not end. We re-cultivate the excavated space according to the approved remediation and reclamation plan. It is based on local conditions, type of land, method of mining, zoning plan, etc. Thanks to reclamation, new areas are created, most often intended for agricultural and forest use. Some will also become part of the territorial system of ecological stability. As part of reclamation, we also create water areas that are used to retain water within the landscape.
    Geological measurements and groundwater studies
    Part of each geological survey is the evaluation of hydrogeological conditions. From its results a hydrogeological study is created and the conditions for quarry operation and mine water management are determined. The water authority and the watercourse administrator determine the conditions under which mine water can be discharged into surface waters. An expert in the field of hydrogeology monitors groundwater and surface water levels and takes samples of mine water. These are then evaluated by an accredited laboratory. The results can be found in the annual report.
