Mining in focus Lime and lime-derived products are essential in the mining and agricultural industries, and demand is expected to increase in the near future, writes Dr Nicolaas C. Steenkamp. D espite its importance, lime does not receive a great deal of attention in the mainstream financial media. More ‘glamourous’ commodities like copper, cobalt, and lithium have hit the headlines lately, e specially with the development of typical Fourth Industrial Revolution technologies. Lime, however, is a key component of these commodity value chains. Late last year, the copper price increased substantially on the back of a bullish outlook for the future of the electric vehicle (EV) market. Based on current figures, EVs will require three times the amount of copper that is required by fuel-driven engines. Several European countries are planning to replace most fuel engines with EVs in the next two or three decades. Add to this figure the amount of copper wiring that will be required for all the recharge docking stations, and the potential of copper in the near future increases exponentially. One of the critical supply resources that are set to also benefit from the current uptick and anticipated future higher demand for copper, are lime products, specifically quicklime. The lithium used in the rechargeable batteries also requires lime products during the processing of the primary lithium-bearing salts. The demand for higher yields of agricultural products on smaller surfaces of land is another future growth point for lime. As the world’s population continues to grow, more pressure is placed on food producers to supply the demand, yet have limitations in terms of the size of workable land and freshwater constraints. Lime is one of the agricultural products that is essential for ensuring soil remains productive and continues to provide high harvests. Drivers of demand According to Breton Scott, managing director of Bowline Professional Services, lime products have a wide range of application, with demand being driven from sectors like construction, agriculture, and mining. Organic and inorganic chemistry use lime as binding agent, collector, or precipitant. In the paper and pulp industry, it is added as binding agent and for basifying.
