Abstract

Enhanced efficiency of diamond ore extraction and processing is achievable with the creation and implementation of:
— correct ratio of surface/underground mining of kimberlite ore bodies;
— new underground geotechnologies for kimebrlite pipes, with no-man approach, including robotic mining machinery;
— underground geotechnology with backfill made of milltailings;
— underground mineral processing using mobile and movable processing plants fitted with the equipment based on X-ray separation for detecting diamonds in a piece of kimberlite;
— technologies of deep diamond surface cleaning.

The choice of processing flowcharts and equipment is first of all conditioned by relatively high density of diamonds as against the bulk of host rocks and minerals, their natural hydrophobic behavior, fluorecence ability under X-ray radiation, as well as by the requirement to preserve diamond crystals during disintegration and shipment. Diamond recovery must reach 92–98%. The most popular methods of diamond extraction are gravity and radiometric beneficiation, in particular, float-and-sink separation (FSS) in cyclones and X-ray fluorescent separation (XFS). Currently, the main economic criterion of a technology quality is the maximum yield of the marketable product per tone of ore, i.e. the ratio of output “product” to input “product” should tend to unit. Even higher improvement of diamond ore mining and processing efficiency can be reached with the design and manufacture of new high-performance automated groups of machines based on ore grading equipment using methods of detecting and taking diamond kimberlite out from the overall flow of rock material:
— Dual-energy X-ray absortiometry (DXA);
— Positron emission tomography (PET);
— Neutron radiography and spectroscopy.

This is the last part of the article. The first part was published in Gorny Zhurnal, 2015, No. 2.
The authors appreciate participation of S. S. Bondar, Consulting Geologist, ALMAZINTECH — Consulting and Engineering, in this research work.
