High grade refractory bauxite from Bonasika Mine in Guyana
First Bauxite produces high grade, low impurity bauxite with raw ore alumina contents at 63% and, when sintered, up to 93% alumina. Using our different mine sources we can supply raw bauxite or sintered from 88% to 93%. First Bauxite serves North America as the only non-Chinese owned or sourced supply of high grade refractory. But the applications do not stop there.
Other applications for First Bauxite’s high grade bauxite include water treatment, a full range of ceramic proppants, flame retardants, welding fluxes, certain abrasive markets, and steelmaking slags.
The high grade bauxite is not a replacement for ordinary non-metallurgical bauxites and not even for other Guyanese bauxites which are lower alumina or higher in iron. The extremely low impurities make this bauxite stand out in a class of its own.
The high corundum with a minor mullite phase present an excellent material for hot strength, refractoriness and resistance to chemical attack or abrasion. Excellent in castables with low alkalis and low porosity.
As a “sweetener” for certain products, First Bauxite can add alumina units and it makes a great feedstock for higher grade alumina processes, such as Brown-Fused Alumina (BFA).
The low silica and low impurities make First Bauxite’s Calcined product a superb choice for steelmaking slag conditioning.
In November 2019, a new wash plant started up raising production to 30,000 tpm raw ore. Since then shipments have been made to North and South America, China, India, Europe including Ukraine, and Africa.
The single product line raw bauxite contains 63% Al2O3, and on calcining yields 93% Al2O3, with low iron and impurity levels. Some calcining has been conducted in the USA to achieve high density (3.45 g/cm3), low porosity products, and as feed for brown fused alumina manufacture.
First Bauxite LLC (FBX) is a natural resource company engaged in the exploration and development of bauxite deposits in Guyana, South America. Its wholly owned subsidiary, Guyana Industrial Minerals Inc. (GINMIN), is the mining arm producing washed bauxite at the rate of 30,000 MT per month. First Bauxite is marketing the high-grade bauxite globally as a raw material for refractories, for aluminum sulphate production, as a UHSP deep-well proppant in the oil industry, plus as an abrasive and steel making slag conditioner.
First Bauxite is shipping bauxite in ocean vessels from its recently constructed wharf at Sand Hills on the Demerara River, about 21km east of the company’s Bonasika bauxite mine. Until now, bulk vessels had to receive raw material barged down the Demerara River to Georgetown for transloading.
