MINING CHEMICALS threefold improvements in settling rates, approximately 50 % reduction in reagent dosage, increased water recovery, and reduced moisture suitable for dry stacking. Successful validation at both laboratory and industrial scales confirms the robustness and scalability of this chemistry-led approach across different commodities.
AECI’ s mineralogy-driven reagent design it says represents a significant step forward in flotation optimisation.“ AECI’ s participation at EXPOCOBRE provided an important platform to engage with industry stakeholders, share technical expertise, and showcase solutions that support safer, more efficient and sustainable mining operations.”
BME Metallurgy on sustainable next-generation mining chemicals
BME Metallurgy says it is advancing next-generation mining chemicals to help operations respond to rising orebody complexity and intensifying sustainability demands across the mineral processing value chain.
“ Orebodies are becoming more refractory, with higher impurity levels and lower head grades, requiring the processing of larger volumes and often finer grinding to liberate valuable minerals,” said Daniel Verwey, Business Development Manager at BME Metallurgy.“ This increases energy demand and places additional strain on downstream processes.”
He added that water scarcity, rising input costs, stricter environmental, social and governance( ESG) requirements, as well as tightening regulations around emissions and chemical use, are sharpening the focus on efficiency and responsible processing.“ Meanwhile, miners are expanding further into critical metals such as rare earth elements, while navigating supply chain volatility.”
Lefa Masiuana, General Manager at BME Metallurgy, said that with over 40 years in the industry, the company has evolved into a solutions provider.“ We specialise in the supply of high-performance reagents and tailored technical support that prioritises measurable improvements in grade, recovery and operational efficiency.”
The company’ s regional footprint supports reliable supply and rapid response.“ BME Metallurgy offers application support,

Safety, Health, Environment and Quality( SHEQ) compliance, training, audits and process optimisation,” he added.
Verwey said that variable mineralogy, higher impurity levels and finer particle sizes require optimised flotation collectors, depressants and modifiers.“ BME Metallurgy invests in R & D, test work and custom formulation to meet these challenges,” he said.
EVERY
HEAP IS DIFFERENT
We’ ve designed and built heap leach projects since heap leaching was first developed in the early 1970s.
