Import Bentonite(Green, Red & White) — Buy in Bulk from Supplier in India

Bentonite from R.K Mineral Cor. is a naturally occurring smectite clay offered in three colour variants, green, red and white, each with distinct oxide compositions mined from deposits in Madhya Pradesh, India. The source data records silica content at 54.65% for white, 57.23% for red and 51.92% for green; alumina at 16.4%, 12% and 13.89% respectively; iron oxide at 10.15%, 13.13% and 13.14%; titania at 1.2%, 1.5% and 1.3%; lime content at 1.2%, 0.8% and 1.1%; magnesia at 2.02%, 3.2% and 5.1%; and loss on ignition at 8.8%, 13.53% and 12.5%. All three variants share a pH of 8.09 to 8.3, placing them in the mildly alkaline range typical of sodium or calcium bentonite suited to industrial binding and absorption roles. The material is supplied as raw lump form, not pre-processed powder, which affects milling requirements and end-use preparation costs for buyers.

The colour variation reflects differing iron and magnesium content: the red variant carries the highest iron oxide and loss on ignition, suggesting stronger colloidal and thermal reactivity, while the white variant holds the highest alumina and silica, pointing toward superior refractory and adsorbent properties. Green bentonite sits between the two on most oxide metrics, with elevated magnesia that may enhance thixotropic behaviour in suspension applications. Buyers should note that these figures represent the supplier's own assay data rather than independent certification, and batch consistency should be verified against declared tolerances. Standard industrial practice for foundry-grade bentonite demands 8-12% moisture, 25-35% swelling index and 70-90% montmorillonite content, values a buyer should request from R.K Mineral Cor. to confirm suitability. The lump form implies a need for on-site or third-party pulverisation and classification to target mesh sizes, typically 200 mesh for drilling mud or 100-150 mesh for foundry bonding.

Primary applications span foundry sand bonding, drilling fluid additive, iron ore pelletising, civil engineering waterproofing and cat litter absorbent manufacture. The red variant's elevated iron oxide suits metallurgical binding, the white variant's purity supports pharmaceutical and cosmetic grade processing, and the green variant's balanced chemistry fits general industrial absorbent use. Importers should request a current certificate of analysis, confirm montmorillonite content by XRD or methylene blue test, and establish whether the lumps require additional processing before shipment. The supplier's location in Katni, Madhya Pradesh, places it near central Indian rail and road corridors, though buyers must verify port routing, container loading capability and any export grade licensing given the supplier's imported tier status and zero recorded response rate.

R.K Mineral Cor. is located at Sawarkar Ward, Nai Basti, Katni, Madhya Pradesh 483501, India. The supplier holds an imported tier classification on the platform and a harbor trust tier, though its response rate stands at 0.00% with zero average response hours recorded. The address places it in an inland mining district rather than a coastal export hub, meaning buyers should confirm whether the company handles export documentation directly or works through freight forwarders. No verified turnover, employee count, factory certification or client references appear in the available profile data.

The listing offers three bentonite colour variants with assay data but does not state production capacity, stockholding, milling equipment, quality control laboratory accreditation or export experience. The raw lump form and absence of mesh size specification suggest the material may be run-of-mine rather than processed to industrial grade. Buyers should treat the oxide percentages as indicative only and request independent laboratory verification against API or OCMA standards before committing to volume orders. The lack of response history means direct enquiry follow-up may require alternative contact channels or local representation in India.
