Pyrite (FeS2) is usually a waste from complex sulfide ores. Yet, it may be a remediation additive for calcareous soils deficient in iron (Fe) and other micronutrients such as copper (Cu), zinc (Zn), and manganese (Mn). In this study, leaching experiments were conducted under laboratory conditions and a 30-day pot trial (with wheat) to evaluate the effect of applying different amounts of pyritic tailings on micronutrient and heavy-metal concentrations in a calcareous soil and on crop growth (dry-matter production). The application of pyritic tailings to the calcareous soils improved the levels of Fe, Cu, Zn, and Mn, and dry-matter biomass of wheat also significantly increased. The heavy-metal contents in soil and plant were well below the permissible limit for soil and plants.

Use of waste pyrite from mineral processing plants in soil remediation Aydın, Gülşen; Arol, Ali İhsan; Department of Mining Engineering (2011) Pyrite (FeS2) is commonly present in complex sulphide ores in significant amounts. After the enrichment of such ores by flotation, pyrite is either produced as a separate concentrate and sold to acid manufactures or removed and disposed off as tailing. Due to lack of demand from manufacturers, most of pyrites is usually disposed off as tailing. Therefore, pyrite is usually a waste from complex sulphide ores. Yet, it may be a remediation additive for calcareous soils and calcareous- alkali soils deficient in...
Influence of mineralogical characteristics on rheological behavior of tailings slurries Aktaş, Berke Beste; Altun, Naci Emre; Department of Mining Engineering (2022-8) The gradual depletion of high-grade ores force mining operations to process ores to finer particles to extract valuable minerals. With the increased amount of fine particles and, in some cases, high clay mineral content presence, complex rheological behaviors in phases including suspensions, such as high viscosity and high yield stress have been observed, causing a decrease in the performance of certain mineral processing operations. Through the study, rheological characteristics of ore tailings slurries wi...
Alkali-silica rectivity and activation of ground perlite-containing cementitious mixtures Ünsal Sağlık, Aslı; Erdoğan, Sinan Turhan; Department of Civil Engineering (2009) Perlite is a volcanic mineral. The latest investigations on ground perlite showed that it is suitable for pozzolanic usage. Thus, it is of vital importance especially for countries rich in perlite such as Turkey. The aim of this study is to investigate the advantages and problems associated with using perlite in concrete and to identify accurate methods and amounts of use for producing durable cementitious mixtures. Within the scope of this study, the alkali-silica reactivity of perlite containing cementiti...
EVALUATION OF PYRITIC TAILINGS FROM A COPPER CONCENTRATION PLANT FOR CALCAREOUS SODIC SOIL RECLAMATION TOZSİN, Gülşen; Arol, Ali İhsan; ÇAYCI, GÖKHAN (2014-01-01) This study was aimed to investigate the feasibility to use waste pyrite and sulphuric acid produced from waste pyrite for the reclamation of calcareous sodic soils. The final aim is to displace Na from an exchange complex and replace it with Ca, leading to a decrease in pH and exchangeable sodium percentage (ESP) and an improvement of soil structure. A fertility of the soil may also be enhanced by this technique since waste pyrite can be rich in several micronutrients. An additional advantage to this strate...
REACTIVITY OF MARBLE WASTES FOR POTENTIAL UTILIZATION IN WET FLUE GAS DESULPHURIZATION Altun, Naci Emre (2016-01-01) Wastes of most marble types are distinguished with their superior CaCO3 content and potential to utilize them as an alternative to limestone. Control of SO2 using marble wastes in wet flue gas desulphurization (WFGD) units of coal fired thermal power plants is an important opportunity. In this study, nine types of marble wastes were evaluated in terms of their ability to dissolution (reactivity) in an acidic environment. The reactivity was expressed as fractional conversion with time with respect to the che...
