Mining the fourth industrial revolution way is the future says industry expert, Andrew Lane.

Innovation is imperative for the future of mining in South Africa. Industry expert, Andrew Lane proposes that leveraging on new information, mining technologies and energy knowhow, which are the hallmarks of the fourth industrial revolution, should set the scene for success.

Lane who is Africa Energy and Resource Leader at Deloitte, engaged students at a recent guest lecture hosted by the University of the Free State’s Business School on the Bloemfontein Campus. “The future is intelligent mining. It’s not just about technology; it’s about changing the way you do business,” he said.

Transforming traditional to trailblazing
“What gives you sustainable competitive advantage is the rate at which you innovate,” said Lane. Design paradigm shifts in the South African mining industry may have resulted in about 100 000 job losses during the past four years. However, mining companies stand to achieve significant gains through applying innovation.

Despite most of South Africa’s mines nearing the end of their lives, mining remains a large employer and investor attractor which ensures that the country holds a competitive advantage in the global economy. Lane is adamant that, “even though we have declined from 20% to 5% in terms of GDP contributions, mining remains a large contributor to export earnings”.

Reaching resource-rich regions
While some physical resources are inaccessible using current technology, “new mineral-processing technologies help tap into previously uneconomical mineral deposits”, according to Lane. In addition to the environment, 3D visualisation cameras can track employees and equipment in the bowels of the earth.

More mining, less loss
Integrating mining, energy, and information technology will ensure that companies reduce people, capital and energy intensity, while increasing mining intensity. The impossible can be achieved if technology is used well for developmental outcomes, employment, and improving standards of living.

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
