Serpentinite is composed of minerals of the serpentine group. Minerals in this group are formed by serpentinization, a hydration and metamorphic transformation of ultramafic rock from the Earth’s mantle. The alteration is particularly important at the sea floor at tectonic plate boundaries.

The raw materials for manufactured sand are widely sourced, encompassing three main categories: natural rock, industrial waste residue, and construction debris. Specific application scenarios and advantages are as follows: ‌Granite‌ ‌Characteristics‌: High quartz content (up to 60% or more), low sulfide content, compressive strength of 120-200 MPa, well-rounded particle shape, and reasonable gradation. ‌Applications‌: Suitable…
