This study found that coarse pineapple waste of any ratio can be molded into product.
If the particle size is coarse, the waste particle does not interact with the ceramic matrix and is simply encapsulated [31, 32].
In this study, primarily some important material properties of fine and coarse basalt waste, taken from basalt processing plants in Diyarbakir, such as sieve analysis, chemical analysis, specific gravity, water absorption, Los Angeles abrasion loss value, soundness of aggregate by Na2SO4, flakiness index and stripping strength were determined.
Alternatively, tailings may be returned to the mine (in-pit storage or backfilling) or mixed with coarse mine waste (co-disposal).
Alumino-silicate materials are coarse aggregate included waste concrete and fired kaolin (metakaolin) at 800°C for 3 h, both passing a sieve of 90 μm.
Aluminosilicate materials used in this investigation are fired kaolin clay and coarse aggregate included waste concrete, both well-grinded and passing a sieve of 90 μm.
Mineralogical characterization of the raw materials was done using X-ray diffraction analysis as represented in Figure 2, where coarse aggregate included waste concrete has a major content of quartz and little calcite content.
The 35 %–40 % reject material consists of two components: coarse coal processing waste (CCPW) larger than 100 mesh (150 micron) size or in some cases larger than 3 mm (1/8 inch) size, and fine coal processing waste (FCPW) or slurry generally less than 100 mesh sizes.
Coal refuse typically consists of two size fractions: (1) coarse coal processing waste (CCPW), which is generally larger than 150 microns (100 mesh) in size and in some cases, is larger than 3.2 mm (1/8-inch) in size; and (2) fine coal processing waste (FCPW), which is generally a slurry (± 15% solids content) with solids being less than 150 microns (100 mesh) in size.
