Import Bentonite Ore — Buy in wholesale FOB from Supplier in Turkey

Aknur Elektronik Madencilik supplies calcium bentonite ore from Turkey with a silica dioxide content of 71.44% and aluminium oxide at 14.65%, positioning it within the range typical for foundry-grade calcium bentonites rather than the higher-swelling sodium bentonites favoured in oilfield drilling. The material carries a loss on ignition of 6.57%, calcium oxide at 2.16% and magnesium oxide at 2.77%, with iron oxide and titanium oxide as minor constituents at 0.93% and 0.21% respectively. The whiteness measurement of 80-86% and swelling ratio of 1/1.16 indicate moderate expandability, a characteristic that suits bonding applications where excessive swelling would compromise mould integrity.

The ore's calcium-based chemistry means it absorbs water less aggressively than sodium-activated counterparts, producing lower viscosity suspensions and weaker gel strength, traits that foundry engineers often prefer for ferrous casting where controlled permeability matters more than high yield. The 71.44% SiO2 content reflects substantial siliceous gangue, typical of Turkish calcium bentonite deposits formed from altered volcanic tuffs and ash beds in the Anatolian region. Importers should note that this composition profile aligns with API 13A Section 9 non-treated bentonite specifications only in limited parameters, and would require sodium carbonate activation for drilling-fluid compliance.

Primary buyers include steel mills requiring bentonite for pelletising iron ore fines, foundries using it as a green-sand bonding agent, and civil engineering contractors deploying it as a geotechnical sealant. The 1/1.16 swelling ratio suggests suitability for environments where moderate water absorption is desirable without the dimensional instability of high-swelling grades. Packaging and moisture content at shipment are not stated in the source data; buyers should specify whether they require dried, crushed, or bulk raw ore, and confirm the fraction size distribution with the supplier directly.

Aknur Elektronik Madencilik Gida Sanayi Ve Dis Tic. Ltd. maintains its registered address in the Zuhtupasa neighbourhood of Kadikoy, Istanbul, at Bagdat Caddesi Partas18, third floor, indicating an administrative and trading operation rather than extraction or processing facilities at this location. The supplier carries a harbour trust tier and shows a response rate of 0.00% with zero average response hours in the available data, which signals that buyer enquiries through the platform may go unanswered or that the profile is not actively monitored. No information is provided about mining concessions, processing plant capacity, laboratory accreditation, or export licensing within the source material.

The company name combines electronics, mining, food and foreign trade activities, a breadth that suggests a trading house structure rather than a specialist bentonite producer. Buyers should verify whether the firm sources ore from third-party Turkish miners or operates its own quarrying rights, and should request chain-of-custody documentation to confirm origin. The listing does not state ISO certification, API licensing, or membership in trade bodies such as IMFOA or Turkish Mining Association; these should be confirmed directly with the supplier before contractual commitment.
