Mining

Basic mining process is systematic open cast - semi-mechanized as per the following stages:

A) Mine development - overburden removal.

Since the bauxite occurs close to the surface, with a shallow overburden (at places it is exposed at the surface itself). Mine development is carried out by direct removal of overburden using excavators. Drilling / blasting also done wherever required. Open cast mine benches are developed to facilitate proper bauxite excavation.

B) Pre-Mining grade assessment of the area to be mined by trenching / pitting and drilling bore holes at the exposed surface.

Systematic sampling / analysis is done to ascertain grade at various point. Grade wise volumes available are recorded in the plan. Exploitation phase is planned based on the above inputs.

Excavation

This operation is carried out systematically through drilling, blasting and mucking, under the guidance and supervision of qualified and govt. approved blaster, geologist and mining engineer.

Excavator and dumpers remove the blasted and loosened material. The company has its own set of mining machinery (details given later) and also hires respective items whenever required additionally.

Sizing & Sorting

This operation is carried out for sorting materials according to their size to obtain the best quality in our finished goods.

Grading

Quality wise sorted materials are graded in different categories like High Grade, Medium Grade & Low Grade in order to obtain the best quality Calcined Bauxite for the customers as per their requirements.

Calcination

Testing

We have our own in house testing facility available. The laboratory is well equipped and staffed to undertake conventional wet chemical analysis as well as for rapid instrumental determinations of various elements in raw bauxite and calcination bauxite.
