1. Basic provisions

Paragraph 1. General requirements of industrial safety

1. These rules of ensuring industrial safety (further - Rules) are developed for the hazardous production facilities conducting works on conversion of solid minerals according to the subitem 14) of article 12-2 of the Law of the Republic of Kazakhstan of April 11, 2014 "About civil protection" (further - the Law "About Civil Protection") and determine procedure for the organization and ensuring industrial safety during the designing, construction, operation, expansion, reconstruction, upgrades, preservation and liquidation of hazardous production facilities by okuskovaniye (agglomeration, briquetting, okomkovaniye), enrichment, crushing and operation of crushing and sorting portable and collapsible crushing and classifying sections and enrichment installations (further - factories).

2. In these rules the following basic concepts are used:

1) turnover water supply - the system of industrial water supply with water recirculation providing its necessary cleaning on condition of permanent use of water by her same consumers;

2) sewage - the waters which are taken away after use in household and productive activity of the person which are exposed to necessary cleaning taking into account their further use;

3) enrichment in the heavy circle - process of gravitational enrichment in the liquids or suspensions having intermediate density between density of the divided minerals;

4) enrichment products - the products received in the course of mineral enrichment: concentrate, intermediate product, tails;

5) gravitational enrichment - process in which separation of the mineral particles differing in density, the size or form is caused by distinction of nature and speed of their movement under the influence of gravity and resistance of the circle of separation;

6) grokhocheniye - the process of separation, material on fineness classes performed on devices (grokhota) with the sifting surfaces;

7) classification - process of separation of granular and polydisperse particles of raw materials, heterogeneous by the size, into classes of different fineness by means of grokhocheniye, hydraulic (pneumatic) classification or in centrifugal field;

8) enrichment on concentration tables - process of gravitational enrichment in thin sheet of water, flowing on the slabonaklonny flat sound board with narifleniye making back and forth motions in the horizontal plane perpendicular to the direction of movement of water;

9) concentrate - product of enrichment of mineral raw materials in which content of valuable components is higher, than in initial material (ore) and other products of similar transactions of enrichment;

10) drying (in enrichment of mineral raw materials) - the process of dehydration of materials, including enrichment products based on evaporation of moisture when heating;

11) the tailings dam (shlamokhranilishche) - the construction intended for stacking of dump products of conversion of raw materials (enrichment tails), their sedimentation, department from tail pulps of the technical water used for turnover water supply;

12) tails - the waste of process of enrichment consisting generally of rock-forming minerals and containing insignificant quantity of useful components which additional recovery is in some cases reasonable and technology possible;

13) condensation - process of separation of pulp into the condensed product and liquid phase (discharge) resulting from sedimentation (movement) in pulp of firm particles by gravity or centrifugal forces;

14) magnetic enrichment (magnetic separation) - the process of separation of pieces of raw materials and mineral grains based on distinction of magnetic properties of the divided components;

15) enrichment of mineral raw materials - set of processes of conversion of mineral raw materials for the purpose of allocation from it useful components with the concentration exceeding their content in initial raw materials;

16) dehydration - process of decrease in content of water in raw materials conversion products;

17) crushing - the process of destruction of lumpy, mineral raw materials under the influence of external mechanical forces by crush, splitting, blow, cut or their combination performed in crushing aggregates;

18) crushing - process of grind of mineral raw materials as a result of the shock and using-up impact of the crushing circle (spheres, cores) and raw materials for the purpose of disclosure of useful components and rock-forming mineral aggregates, and also for ensuring necessary fineness of process of enrichment;

19) flotation - the process of mineral processing based on difference of superficial properties and the selective contact of particles of minerals to interface of phases: liquid - gas, liquid - liquid;

20) floatation reagents - the organic and inorganic substances entered into floatation process for the purpose of regulation of floatability of minerals;

21) electric separation - the process of separation of particles based on distinction in sizes of electric charges by change of trajectory of movement of these particles in electric field.

Engineering procedures need to be made with observance of the production schedules developed and approved by the head of the organization operating factory (further - production schedules).
