Abstract

Sposób przetwarzania odpadu flotacyjego z procesu wzbogacania rudy miedzi, zawierający etap wstępnej aktywacji termicznej oraz mechanicznej, podczas których odwodniony odpad zawierający w składzie minerały węglanowe, minerały ilaste oraz kwarc, poddaje się obróbce termicznej w temperaturze poniżej 850°C, następnie schładza do warunków otoczenia oraz mieli. Obróbkę cieplną odpadu flotacyjnego prowadzi się do utworzenia aktywnych hydraulicznie związków bez udziału fazy ciekłej. Następnie w uplastycznionej przez dodatek wody masie odpadu, zawierającej fazy mineralne aktywne hydraulicznie oraz domieszkę poryzującą, inicjuje się reakcje syntezy uwodnionych tlenków wapnia i magnezu, krzemianów wapnia i magnezu oraz glinokrzemianów wapnia do uzyskania porowatej stałej masy z fazami mineralnymi tobermorytu włóknistego oraz hydratu krzemianu wapnia C-S-H(I) krystalicznego o wytrzymałości na ściskanie co najmniej 7 MPa. Procesy utwardzania masy prowadzi się w temperaturach z zakresu 20°C - 250°C, pod ciśnieniem 0,1 do 3 MPa oraz wilgotności względnej 40%, w tym pary nasyconej, w czasie 4 — 20 godzin.A method for processing flotation tailings from copper ore enrichment, comprising a preliminary thermal and mechanical activation step, during which the dewatered tailings, containing carbonate minerals, clay minerals, and quartz, are subjected to thermal treatment at temperatures below 850°C, then cooled to ambient conditions and ground. The thermal treatment of the flotation tailings is carried out to form hydraulically active compounds without the participation of a liquid phase. Subsequently, in the waste mass plasticized by the addition of water, containing hydraulically active mineral phases and a porous admixture, synthesis reactions of hydrated calcium and magnesium oxides, calcium and magnesium silicates, and calcium aluminosilicates are initiated to obtain a porous solid mass with mineral phases of fibrous tobermorite and crystalline calcium silicate hydrate C-S-H(I) with a compressive strength of at least 7 MPa. The mass hardening processes are carried out at temperatures ranging from 20°C to 250°C, under pressure of 0.1 to 3 MPa and relative humidity of 40%, including saturated steam, for 4 — 20 hours.
