5. Byproduct use studies of waste granite sludge failed to find a product that would be economically feasible to produce. 6. Studies of ultimate sludge disposal indied that more industry cooperation, design changes and better construction of waste lagoons would greatly improve waste sludge disposal.

In this work, the waste stone sludge obtained from the granite and marble stone processing factories was used for the manufacture of artificial stones using vibratory compaction in a vacuum environment. The results obtained showed that water absorption and density increased, and the flexure, compressive, and tensile strengths decreased with increase in the content of the waste stone sludge.

Best available techniques Calcareous sludge can be used to: neutralize acidic industry byproducts or contaminated agricultural land desulphurise the fumes produced by highpower thermoelectric plants as additive in hydraulic mixtures, plasters. produce paper fillers, polymeric fillers (PVC), water paints, artificial stones. Granite sludgeproduced by disk saws or by the

Another solid waste generated by the marble and granite units is the cutting waste which results from cutting slabs into the required dimensions. After the stone has been cut to the specific dimensions, the slabs are finished either by polishing or texturing, as requested. The polishing operation is fully automated with the

dry. This water carries large amounts of stone powder. Eventually, the sludge dries in the sun and its particles become airborne. This causes air pollution problems for the surrounding area. Another solid waste generated by the marble and granite units is the cutting waste which results Marble and Granite Waste: Characterization and

The following waste materials were investigated: silica sludge, superfluous clay in the quarry, waste glass, and residue from the polishing process of different types of stone. SiC and MnO(2) were selected as ing agents. Feldspar containing minerals and scrap glass were added in order to lower the softening point of the waste materials.

Downloadable (with restrictions)! Since the beginning of the sixties, Sardinia (Italy) has established itself as a granite production area both nationally and internationally. The activity of quarrying and processing of marble began in the Orosei area (northeast Sardinia) by the end of the same decade. This study is aimed at describing the troubled time experienced by the Sardinian granite ...

01/03/2020 · The management of residual sludge from dimension stone processing activities (EWC 010,413) represents a large concern for stone industry. Such sludges are characterised by a fine size distribution, high heavy metal contents and, potentially, TPH (Total Petroleum Hydrocarbon) contents.

7 tons of rock dust (granite sawdust) on a yearly basis (Barrientos et al., 2010). 8 The use of waste and byproducts from mining and industrial activities ( fly 9 ash, dewatered sludge, quarry fines, mine tailings, etc.) in geotechnical engineering 10 projects constitute a sustainable waste management approach ( Borghetti et al.

Wastewater treatment Wastewater treatment Sludge treatment and disposal: The residue that accumulates in sewage treatment plants is called sludge (or biosolids). Sewage sludge is the solid, semisolid, or slurry residual material that is produced as a byproduct of wastewater treatment processes. This residue is commonly classified as primary and secondary sludge.

Another solid waste generated by the marble and granite units is the cutting waste which results from cutting slabs into the required dimensions. After the stone has been cut to the specific dimensions, the slabs are finished either by polishing or texturing, as requested. The .

3 Stone Waste The greatest waste concern in the stone industry is stone itself, specifically in the forms of overburden, screening residual, wastewater sludge, baghouse fines, and stone There is wide variation in waste generation across the industry due in .

12/07/2016 · Residual sludge coming from dimension stone working activities represents a serious environmental and economic problem for both stone industry and community. Indeed, most of the time, residual sludge is landfilled because of the difficulties to recover it; such difficulties are mainly connected to local legislation and to a lack of proper protocols. In general, two different egories of ...

The following waste materials were investigated: silica sludge, superfluous clay in the quarry, waste glass, and residue from the polishing process of different types of stone. SiC and MnO(2) were selected as ing agents. Feldspar containing minerals and scrap glass were added in order to lower the softening point of the waste materials.

The sludge slime was collected directly from the ornamental stone cutting industry (ICMG) and analyzed for its chemical composition. Both sludge slime and raw materials were analyzed using (Xray fluorescence, EDX700, Shimadzu). The mineral constituents of the dried and sintered sludge slime were determined using xray
