## 2 Preliminary Qualitative Analysis  
A precise analysis of this issue was conducted in the work of [6] in two dimensions: environmental and economic (CE idea). The first criterion of this analysis consisted of environmental conditions regarding the arduousness of waste utilization. The basic criterion here was the recognition whether the examined waste is considered dangerous or whether it is the so-called neutral waste. The second criterion was the location of the examined mining waste treatment facility. Whether the given facility is located in legally protected areas (e.g., national parks, nature reserves, protected landscape areas, NATURA 2000 areas, etc.) or not. This criterion also took into account the occurrence of the Main Underground Water Reservoirs. In the scope of economic criteria, the first examined aspect was the set of raw materials that are essential for the Polish economy [18]. Therefore, the following were recognized as essential among the rock raw materials: kaolinite clays, crushed and dimensions stones, kaolins, sands and gravels, feldspar raw materials and glass sands. The second aspect taken into account in economic criteria was the type of waste with potential economic significance. Of course, the amount of given waste was also taken into account. Considering the literature analysis, the economic significance is also assigned to the waste, for which it is possible to use them e.g., in reclamation, agriculture, food industry or production of light aggregates. The research also took into account the possible directions of applications of rock raw material waste, which can be grouped in the following manner:  
* Industrial use of clays: the clays mainly consist of loamy minerals, such as kaolinite, illinite, montmorillonite, and other aluminosilicates, as well as other various components, e.g., quartz grains, apatite, granite, iron hydroxide, etc. The potential uses include: multifunctional sorbent-fertilizers designed for the reclamation of sands [19; 20], feed additives, which constitute an important group of preparations in breeding, such as peat humus, zeolites, kaolins, bentonite, and others having a positive effect on production indicators [21; 22], insecticides, and fungicides in order to increase the effectiveness of pesticides [23; 24; 25; 26], food industry use of bentonite clay for storing fruit and vegetables in households [27], and environmental protection use of clay as an absorbent to remove heavy metal ions and purification of industrial and drinking water [23; 28]. * Rock meals: basalt, granite and serpentine materials from mining waste can be used to produce rock meals, which are created from grinding of the rock. Such meals can be used to improve soil properties by enriching it with minerals, such as calcium, potassium, and magnesium. E.g., comprehensive \"remineralisation\" of the soil substrate with basalt meal [29]. Granite meals are useful on heavy soils as well as light, sandy soils, which are poor in loamy minerals because they increase the water capacity of soils, particularly in the humus layer and include many necessary macro-, micro-, and ultra-microelements, which are necessary for the proper growth of plants. In addition, these rock meal plays a sanitary role, preventing the spread of diseases and pests. The serpentinite meal can provide the soils with many microelements, among others iron and phosphorus [30; 31]. * For the production of light, inferior. or hydro-technical aggregates: use of granite waste for the production of aggregates, which allowed to strengthen the strength of aggregates produced and eliminate flux and apply it to various structures (for example, stabilization of landslides and slopes, strengthening of underwater slopes, etc.) [32]. * As a granulate supporting cultivation of plants: granulate contains rock siliceous meal selected from the group of basalt, feldspar, or amphibolite meals.
