Barite Introduction:

Barite is a mineral composed of barium sulfate (BaSO4). It receives its name from the Greek word "barys" which means "heavy." This name is in response to barite's high specific gravity of 4.5, which is exceptional for a nonmetallic mineral. The high specific gravity of barite makes it suitable for a wide range of industrial, medical, and manufacturing uses. Barite also serves as the principal ore of barium. It is also important in the manufacture of paper, rubber and Explosives. Barite is also used in radiology for x-rays of the digestive system. When pulverized, it is added to drilling fluids, which is poured into oil wells during drilling job.

Current Business Activities:

Mining, Grinding and Marketing of Drilling Grade Barites powder and ore to mainly Oil and Gas drilling companies in Domestic and Global Market and export of ore globally respectively.

Grinding Facility

BME has its own following grinding mills, for grinding of barite ore extracted from Gunga Mines.

1. MTM-160, 100,000 (tpy) production capacity.

2. BM-10, 50,000 (tpy) production capacity.

Quality Control

BME has own API certified quality control laboratory for testing & analysis of both barite powder and Ore, however, BME also get production analyzed from independent labs (SGS Pakistan (Pvt) Limited & Qualitest laboratory Karachi) for cross confirmation of test results and Administration control. The only material that conforms to API Specs 13-A releases for sales. Buyers are also encourage to carry out analysis through their own resources:

Storage Capacity

BME has its own storage facility at its mill premises at Khuzdar. To keep an stock of 4,000 tonnes ground barite and 40,000 tonnes raw material (ore / lumps form) to meet emergency requirements of export customers.
