Marble is a metamorphic rock composed mainly of recrystallised calcite or dolomite. Dimension stone, cutting dust, slurry and ground carbonate product are not the same commercial material.
- Class
- Metamorphic carbonate rock
- Common minerals
- Calcite and/or dolomite
- Process distinction
- Dimension-stone production differs from micronized powder
Defining marble feed correctly
Geological marble is carbonate rock recrystallised by heat and pressure. Commercial dimension-stone naming can be broader, so process design needs mineralogical identity.
Cutting slurry or offcuts may be secondary feed, but water, abrasive, metal, resin and mixed-stone contamination can prevent direct product acceptance.
Industrial routes
- Blocks, slabs and decorative stone
- Crushed marble aggregate
- Qualified ground carbonate filler
- Characterised marble residue as secondary feed
Drying and grinding
Dewatering and drying load for wet cutting slurry differs from dry marble offcuts. A standard milling route cannot be selected without feed-form and contamination control.
For calcite-rich feed, PSD, colour and coarse-tail control matter. Dolomitic or siliceous veins change breakage and wear.
Difference from calcite and limestone pages
This page targets metamorphic rock and dimension-stone residues; the calcite page targets mineral/GCC and the limestone page targets sedimentary rock feed.
- Calcite-dolomite mineral balance
- Cutting water and possible contaminants
- Colour and final filler standard
- Dry offcut, slurry or powder feed form
