AMELIORANT EFFECTIVE ACTION ON THE DRILL CUTTINGS
For the first time is investigated the comparative effect of some coagulants (carnallite, phosphogypsum, calcium carbonate,aluminum sulphate, calcium chloride) on the physical properties of drill cuttings. The research results indicate that the drill cuttingshave a high content of sodium cations, their presence is due to the presence of soda, which is introduced with the agent tofacilitate the drilling process. Carnallite and phosphogypsum – wastes of chemical production represents the greatest practicalinterest for the conditions of the Tyumen region. Phosphogypsum (СaSO4 ∙ 2H2O) is sulphate-containing by products obtainedin the production of hydrofluoric and phosphoric acids. The main component of phosphogypsum is calcium sulfate and, therefore,phosphogypsum exhibits acidic properties. As for the major components phosphogypsum contains: СaO – 25–35 %, SO4 –50–58 %, SiO2 – 2–18 %, Al2O3 – 0,1–0,3 %, Fe2O3 – 0,1–0,2 %, P2O5 – 0,5–4,0 %, F – 0,2–2 %, pH – 2,6–6,0. Phosphogypsumis produced in the form of a slurry with a moisture content up to 55 %, sludge in a solid state is finely dispersed and containsmore than 90 % of particles less than 89 microns. Phosphogypsum contains a small amount of impurities (3–4 %) and accordingto the content of the main component (СaSO4∙2H2O) it refers to the raw gypsum of 1–2 grades. Carnallite is a waste productionof Mg and Mg is a raw material for titanium production. It has been usually registered slight admixtures of Br, Li, Rb, Cs, andmechanical particles of clay minerals, hematite, water iron oxides, etc. It is concluded that the introduction of effective coagulantseliminates alkalinity, reduces the hydrophilicity, improves the structure and water resistance of drill cuttings.
