Potential of dolomite industrial waste as construction

Dolomite industrial waste is generated mainly due to the crushing and processing of dolomite stone during mining and production activities. Chemical properties Dolomite CaMg (CO 3) 2, a rock-forming mineral, is primarily composed of calcium oxide, silica, magnesium oxide, and small amounts of aluminum oxide and iron oxide. The mainIf a dolomite crystal nucleus was present, Mg 2+ in dolomite diffused into the calcite lattice, resulting in a decrease in the order of calcite crystals (Hong et al., 2016). In the ordered crystal structure, the particles were regularly distributed and generally stable, and therefore the energy required to destroy the lattice was high.Influence of crystal nucleus and lattice defects on dolomite

Study of Iron-Bearing Dolomite Dissolution at Various

We investigated the dissolution of a natural Fe-containing dolomite [Ca1.003Mg0.972Fe0.024Mn0.002(CO3)2] under acidic conditions (pH 3–5.5) with atomic force microscopy (AFM) at 20 °C and with batch dissolution experiments at 80 °C. Dolomite dissolution proceeded by two identified mechanisms: removal of dolomite layers through Fig. 1 shows the influence of sodium oleate concentration on the flotation recovery of calcite, dolomite, pyrite and chalcopyrite single minerals at pH 10. As can be seen, chalcopyrite floated readily with sodium oleate, followed by calcite, dolomite and pyrite.

Hydrothermal dolomitization and porosity development: An

Dolomitic rocks from the Rio Bonito Quarry, located in the Água Clara Formation, record multistage dolomitization processes linked with porosity development in the southern Brazilian Shield. Dolomitic marble and breccia samples from this unit contain three textural types of dolomite that either are fabric destructive or void-filling phases. To The dolomite in the study area is characterized by a high CaO and a low MgO content (Table 3.1), which suggests partial dolomitization.The amounts of CaO and MgO in the dolomicrite have a positive linear correlation, indicating a sedimentary origin; the CaO and MgO contents of fine-crystalline dolomite and dolo-arenite have, in contrast, a negative Dolomitization an overview ScienceDirect Topics
