Need for Improved Water Efficiency in Mineral Processing Applications Fuels Demand for Dewatering Products
Mine dewatering aids are specifically formed surface-active agents that help reduce the moisture content of mineral aggregates during filtration and subsequent storage applications. These products usually decrease the surface tension of water to remove water from mineral surfaces during filtration and storage. Dewatering aids are mostly used in all wet mineral processing applications to increase the moisture content of filtered cakes as required. Application areas include both sulfide and non-sulfide minerals processing and as well as coal cleansing. Dewatering aid dosage specifications vary extensively based on end-use applications. Dewatering aids can be applied directly or in diluted form and points of application in the process must be carefully selected. Improved filtration of mineral concentrates and better filtration efficiency are primarily driving the Europe and Middle East & Africa dewatering aids for mining market.
In the mineral processing industry, dewatering operations are generally carried out at raw materials or product-handling stage. For instance, after beneficiation or concentration, the ore may require drying to some maximum level to expedite handling. The minerals are very often available as solids, aqueous liquids, or slurries with varying particle sizes. Distinct dewatering technologies are presently being used to dehydrate minerals. Although dewatering is a highly energy-intensive operation that is difficult at lower moisture contents, no special attention is normally given to the technical and economic aspects of the dewatering process applications in the mineral processing industry. This creates new opportunities for dewatering aids for mining market in Europe and Middle East & Africa in the near future. Dewatering aids include surfactants, flocculants, polymers, sulfonates, and sulfates mostly used to control moisture levels and increase throughput in filter applications.
COVID-19 Impact: Improper Supply of Raw Materials Hindered Production, Growth Rate
The COVID-19 pandemic has changed the global economy rapidly, without warning, and severely affecting mining, making a huge impact on the dewatering aids for mining market. After the first few months of the spread of the coronavirus disease, the mining pillar seemed to be relatively stable. However, the outbreak of the COVID-19 pandemic had disrupted the political, economic, financial, and social structures all over the world. In 2020, the consequences of the pandemic reached far extending to limited communication, trade, access to all kinds of goods, and supply chain of raw material services. Moreover, it reduced the demand for and sales of dewatering aids and stopped many economic activities, including production. Growth rates of markets relevant to mining indicate the highest decline for the Europe and Middle East & Africa dewatering aids for mining market. The limits also extended to mining metal ores together with other non-metallic mineral products, and mining and quarrying.
Mining of coal and lignite is at the opposite extreme, and this is the only industry with a positive result that generated demand for dewatering products. Additionally, many governments have allowed mining to continue during the pandemic with limited work staff, raw materials, and restrictions relating to COVID-19 mitigation. This distinguishes this branch of the economy from other industries that have been closed for several months due to government decisions. Additionally, significant changes have been observed in the economic and social policy of most countries, especially in the aspect of government interventionism. Nevertheless, with rapid vaccination drives and innovations in medical technology, the pandemic is nearing its end in Europe and Middle East& Africa. The post-pandemic period offers various opportunities for dewatering aids manufacturers, owing to increased mining activities to flatten the demand curve.
Regulations on Disposal of Mineral Sludge Drive Demand for Dewatering Aids
Industrial sludge and residue sludge hold varying amounts of organic chemicals, toxic metals, chemical irritants, and pathogens, which may cause several diseases. Untreated sludge disposed into rivers and seas negatively affects aquatic life and poses serious health hazards. Moreover, environmental protection standards have laid down sludge disposal laws that constrain pre-treatment as well as measures to be met prior to the disposal or reuse of sludge in agricultural or power generation activities. Thus, there is an increasing need for dewatering aids to meet all the standards in mining waste disposal. Furthermore, the dewatering technology has observed significant advancements with more effective units such as decanter centrifuges, screw presses, and belt presses available in the market. In addition, the demand for metals and minerals has been increasing significantly. As a result, mining companies are investing more in mining activities such as exploration, mining, and material processing. This is likely to propel the Europe and Middle East & Africa dewatering aids for mining market during the forecast period.
On the contrary, well-digested primary sludge is comparatively easy to dewater. Along with the developments in sludge dewatering to achieve the highest solid content, it is also necessary to establish a reliable dewatering index. Most popular dewatering techniques include Capillary Suction Time (CST) and Specific Resistance to Filtration (SRF), but these methods only measure the rate of filtration and do not consider complex variables associated with the dewatering process. In addition, different dewatering aids have varied processes and intensities, which considerably affect the performance of mineral sludge dewatering. This is most likely to restrain the growth of the dewatering aids for mining market in Europe and Middle East & Africa in the upcoming years. Hence, the evaluation of mineral sludge dewatering is critical for any sludge treatment system where optimizing the dewatering process is the primary goal.
