Import Bauxite Ore — Buy in wholesale FOB from Supplier in Indonesia

East Java Antique supplies tri-hydrate bauxite ore from Guinea Conakry origin, with Al₂O₃ content of 44% to 47%, SiO₂ at 2%, and Fe₂O₃ capped at 25%. The material exhibits low reactive silica and minimal CaO (0.1%) and MgO (0.2%), characteristics that reduce caustic consumption during Bayer process digestion. Free moisture is specified at 8% to 10% maximum, with a top size of 0 to 173 mm where 99.5% of material should pass, indicating minimal fines control but coarse fraction acceptance. Annual contract volumes reach 4,000,000 metric tonnes with monthly deliveries of 50,000 to 400,000 metric tonnes over 12 to 60 month terms with rollover extension options.

The tri-hydrate classification indicates predominantly gibbsite mineralogy, which digests at lower temperatures (140°C to 150°C) compared to monohydrate ores, offering energy savings for refineries equipped with low-temperature circuits. The low silica content (2%) is advantageous for minimizing red mud generation and caustic loss, though buyers should still distinguish between quartz and kaolinite fractions in this figure. The 0.1% CaO and 0.2% MgO levels are typical for Guinea-Conakry bauxites and generally favorable, as elevated carbonate minerals can cause scale formation in digesters. The broad size fraction up to 173 mm suggests run-of-mine or lightly screened product; buyers with fixed-feed crushing circuits should assess secondary processing needs at destination.

This bauxite targets alumina refineries, large-scale trading companies, and integrated aluminum producers seeking long-term, high-volume feedstock contracts with geographic diversification from Guinea-Conakry sources. The 12 to 60 month contract structure with extension provisions suits buyers requiring supply security for greenfield refinery projects or smelter expansions. Incoterms, loading port specifics, and payment structures are not provided and must be negotiated directly with East Java Antique. Given the substantial monthly volumes, buyers should evaluate port infrastructure at Conakry, vessel size optimization, and seasonal West African shipping conditions.

East Java Antique is located at Taman Pondok Jati At-7, Geluran-Taman, Sidoarjo attending Sidoarjo 61257, Jawa Timur, Indonesia, though the bauxite ore itself originates from Guinea Conakry rather than Indonesian mines. The trust tier is classified as harbor with zero recorded response rate and zero average response hours, indicating no platform-tracked buyer communication history. This profile suggests the entity operates as a trading company or intermediary rather than a mining operator, with Indonesian offices handling sales and logistics coordination for West African sourced material.

No establishment date, employee count, annual revenue, mining concession details, or client portfolio is disclosed in the available data. The supplier does not list certifications, membership in industry bodies such as the International Aluminium Institute, or audited financial statements. Buyers should independently verify corporate existence through Indonesian company registration, confirm the Guinea-Conakry supply chain relationship via documentation of offtake agreements or export permits, and request proof of prior executed volumes given the large contract sizes marketed.
