Abstract
In this work, the material composition of the ore of the Karamola Deposit is studied. A sample of manganese ore from the Karamola Deposit with a size of 0-120 mm was received for research on the material composition. The manganese mineralization of the sample is represented by the mineral series polyanite-pyrolusite and WADA-psilomelane. Mineral secretions are crystalline earthy structures and mixed formations. Manganese oxides are distributed almost throughout the entire mass of the rock. They are represented by crystallized gel formations, soot, and skeletal structures. Ore gels permeate the rock through cracks, cleavages, leaching voids, pores, cleavage planes and penetrate between the scales of layered minerals and form a variety of forms in the mass of the rock: individual strokes, thread-like cuts, veins, edges, layers, nests. Replacement solutions are siliceous or manganese-siliceous in nature and color the rock in the corresponding color with mineral microparticles: black – manganese, red and red – iron. Rock-forming minerals are mainly represented by quartz. The granulometric composition of an ore sample crushed to the minus 2.0+0 mm class was determined.
