Young generations push record diamond demand but require new approaches by industry
Published: 21 Sep 18
The worldwide demand for diamond jewellery set a new record high of $82-billion in 2017, diamond giant De Beers reported in its “Diamond Insight Report 2018”. The driving forces behind this demand were Millennial and Generation Z (Gen Z) consumers, who, together, accounted for 66% of global diamond sales last year. Millennials means people who are currently in the age range from 21 to 39, when Gen Z covers those who are currently ages 20 years or younger.
Dry separator could arrive in Africa in early 2019 Dry separator could arrive in Africa in early 2019

Screening and vibrating equipment solutions and services provider Aury Africa aims to bring the first dry separator to Africa for trial at a coal mine next year, says Aury Africa business development manager George Sturgeon. Aury Africa, a subsidiary of design and construction coal group Dadi Engineering Development Group, is in discussions with high-technology company Meiteng Technology Group to bring in its Telligent Dry Separator (TDS).
Intensive coal  screening requires  fit-for-purpose equipment Intensive coal screening requires fit-for-purpose equipment
Published: 21 Sep 18
As coal beneficiation is generally a screening-intensive process, screening equipment is an important part of a coal plant and a major investment for the operation, says vibrating and original equipment manufacturer (OEM) and supplier Kwatani CEO Kim Schoepflin. The local coal sector comprises various mine operators, from large global operations to small, emerging miners. Schoepflin points out that owing to this diversity, it is crucial that equipment suppliers understand the needs of individual operators to ensure fit-for-purpose equipment is supplied.
Local coal future depends on economic situation Local coal future depends on economic situation
Published: 21 Sep 18
Coal mining currently provides more than 86 000 jobs locally, and this figure will increase as more junior mines are expected to open in the future, provided that the economic situation “does not deteriorate further”, says coal consulting company XMP Consulting senior coal analyst Xavier Prévost. South African coal production has remained stagnant during the last five years because of a lack of incentives and capital to implement new coal projects. However, production will soon drop drastically because some of the older, larger mine reserves are almost exhausted, he tells Mining Weekly.
R&D on clean  coal technologies crucial in SA R&D on clean coal technologies crucial in SA

The research and development (R&D) of clean coal technologies in South Africa is absolutely necessary, says Fossil Fuel Foundation director and recently retired Department of Science and Technology-National Research Foundation South African Research Chairs Initiative Clean Coal Technology chair Professor Rosemary Falcon. Clean coal technologies are a collection of technologies being developed to reduce the environmental impact of coal during production and in energy generation.
Focus turns to nonexplosives-based rock breaking as quest for safer, more-efficient mining intensifies Focus turns to nonexplosives-based rock breaking as quest for safer, more-efficient mining intensifies
Published: 21 Sep 18
The South African mining industry, once the backbone of economic growth, intensive job creation and development, is declining constantly, owing to the slow rates of research and development into newer, safer, modernised, mechanised and continuous mining methods. A key pillar of improving mining efficiency and safety for personnel – as mining becomes deeper in search of orebodies – is using alternative rock-breaking methods to replace the legacy explosives-based methods.
Supplier grows installed base of  Cavex hydrocyclones Supplier grows installed base of Cavex hydrocyclones Has Video
Published: 21 Sep 18
There is a fast-growing installed base of Cavex hydrocyclone technology in coal processing in both classification and dense-medium separation (DMS) applications, according to mining equipment supplier Weir Minerals Africa. “This is as a result of the lower total cost of ownership achieved by clients using the Cavex hydrocyclones in their operations,” Weir Minerals Africa cyclones product manager Sheldon Gabriel tells Mining Weekly.
Manufacturer ready to commission plant Manufacturer ready to commission plant

Bidvest Commercial Products division Kelmeg Lifting Services (KLS) has expanded its service offering – aimed at improving safety and productivity, particularly with regard to working at height, and the associated lifting, rigging or lashing requirements. The new safety-focused products can assist companies in their quest to achieve zero harm.
Versatile spin filters extend machinery, equipment life Versatile spin filters extend machinery, equipment life
Published: 21 Sep 18
A compressor exposed to abrasive dust, such as those used in mining environments, could become increasingly inefficient and fail internal damage caused by clogged and compromised intake filters, notes RTS Africa Engineering MD Ian Fraser. Additionally, opencast mine dust frequently enters dragline machinery spaces and operator cabins, while the grid floors in many blast-hole drill-rigs’ grid floors allow for dust to enter into the cabin, compromising machinery that affects wear life and performance, and creating health risks.
