Quartz (Lumps & Grains)

Origin

Nigeria and India

Overview

Kresta Earth Resources Limited supplies premium-quality Quartz in the form of lumps and grains, suitable for diverse industrial applications. Our quartz is known for its high SiO₂ purity, low impurities, and excellent physical properties, making it an essential raw material for glassmaking, foundry, ceramics, construction, and silicon-based industries.

Key Features

• SiO₂ Content: 97%–99.5%
• Form: Lumps (25mm–150mm) and grains (0.1mm–10mm)
• Impurities: Low Fe₂O₃ (<0.05%) and minimal alkali oxides
• Moisture: Less than 0.5%

Applications

• Glass manufacturing (container glass, float glass, specialty glass)
• Foundry molds and cores
• Ceramics and refractories
• Silicon metal and ferrosilicon production
• Construction (paints, adhesives, engineered stone)

Geological Context

Quartz deposits are derived from vein-type and pegmatite-hosted systems within granitic terrains of Zambia and surrounding regions. These high-purity quartz bodies form as part of silica-rich magmatic and metamorphic processes.

Deposit Types:

• Hydrothermal quartz veins
• Pegmatite-hosted quartz lenses
• Alluvial and eluvial quartz accumulations

Host Rocks:

• Granites and pegmatites
• Quartz-mica schists
• Metasedimentary belts with silica enrichment

Mineralogy

Composed primarily of Quartz (SiO₂), with minor feldspar, mica, and trace accessory minerals.

Export Logistics

Our quartz (lumps & grains) is transported via road and rail corridors to key export hubs including Dar es Salaam, Beira, and Durban. We offer shipments in bulk, containerized bags, or customized packaging based on customer requirements.
