Indian Mineral Client Signs 23 Sets of Ore Color Sorters After Successful On-Site Quartz & Calcium Carbonate Testing

On‑site Testing & Cooperation Progress

APEX recently welcomed a professional mineral processing customer from India for an on-site factory visit and material test. The customer specializes in mineral raw material processing and brought local ore samples for real machine verification, covering quartz sand and calcium carbonate with four common particle sizes: 25-40mm, 10-25mm, 5-10mm, and 2-5mm.

Our sales and technical team accompanied the client throughout the whole process. We demonstrated the actual operating performance of belt-type mineral color sorters and chute-type mineral sorting machines. The customer witnessed the whole sorting process and was extremely satisfied with the finished product purity, impurity removal effect and stable running performance.

In addition to the excellent machine performance, the client highly praised APEX engineers’ skilled operation, accurate parameter adjustment and rigorous technical attitude. The customer expressed full recognition of our professional manufacturing strength and technical service capability.

After in-depth communication and technical confirmation, the two parties formally signed a purchase contract for 23 sets of mineral sorting equipment on site. The equipment combination includes belt-type ore sorters and chute-type sorting machines which are configured for quartz sand and glass sand processing to meet the customer’s current and future multi-scene mineral production needs.

Current Development Status of India’s Mineral Processing Industry

India is rich in quartz, calcium carbonate and silica mineral resources, supporting a large number of downstream industries such as glass manufacturing, ceramic production, building materials processing and mineral export trade. In recent years, with the continuous improvement of international mineral product quality standards, local Indian mineral enterprises are facing prominent industry pain points.

Traditional manual sorting relies heavily on labor, with high labor costs, low efficiency and unstable product quality. Impurity residues and insufficient whiteness often restrict the export value and market competitiveness of mineral products. Therefore, more and more Indian mineral processors are beginning to eliminate manual sorting and introduce high-precision automatic color sorting equipment to realize production upgrading.

What APEX Brings to Mineral Processors

1. Multi‑particle‑size Adaptive Sorting Solution

APEX mineral color sorters deliver reliable sorting performance across particle sizes from 2 mm to 40 mm, perfectly matching the grading requirements of quartz sand and calcium carbonate raw‑ore materials. With stable impurity removal and precision fine‑sorting capability, our equipment effectively boosts mineral whiteness and improves finished‑product qualification rates.

2. Dual‑machine Options for Diversified Production Needs

We supply both belt‑type and chute‑type mineral sorting machines. Belt‑type sorters are ideal for large‑granule ore separation, while chute‑type units are specially optimized for fine‑grained quartz sand and glass‑sand processing. This flexible dual‑solution setup allows customers to reserve production capacity for upcoming glass‑sand projects, achieving one‑time equipment investment for multi‑commodity processing.

3. Cut Operational Costs & Lift Product Added Value

Automated optical sorting replaces labor‑intensive manual picking, substantially lowering long‑term labor expenditure. High‑consistency sorting outputs help mineral processors produce premium‑grade materials that meet strict international export standards, creating higher‑value finished products and stronger market competitiveness.

4. End‑to‑end Professional After‑sales Support for Overseas Clients

From sample testing and customized solution design, through on‑site machine commissioning and operator training, to long‑term after‑sales maintenance, APEX provides full‑cycle one‑stop technical services for global mineral‑processing partners. Our rich practical experience in ore‑sorting projects guarantees stable and worry‑free operation of your production line.
