Today, phosphoric acid producers face significant challenges in the areas of environmental compliance, chemical efficiency, plant productivity and product quality improvement. Metalub has developed a broad range of additives to help phosphoric acid producers overcome each of these challenges efficiently and cost-effectively.
Metalub is at the forefront of particle surface chemistry upon which successful flotation depends. This has been achieved by over 15 years of research and development in molecular and surface chemistry, along with feedback from our clients. The strength of our chemistry and process know-how lies in the fact that we can customize solutions to fit each individual phosphate deposit. And since the ore varies in composition, we must vary the process and adapt it to each individual case. Therefore, in addition to our standard flotation reagents, we develop tailor-made products in close cooperation with our clients.

Metalub defoamers function by altering the surface tension of the liquid, which destabilizes the foam and therefore enlarge capacity, improve efficiency, maximize chemical reactions and contribute to a clean and safe working environment. Metalub defoamers were developed along two decades of laboratory trials and field experience together with our partners. below are listed some of Metalub defoamers benefits: Inert to Process – Doesn’t interfere with phosphogypsum cake porosity. Environmental Friendly – Follow latest EU and US regulations. Thermal Stability – Stable at extreme temperatures up to 140 Celsius. Chemical Stability – Circulate in the system for prolong periods. Inert to Elements – No chemical reaction with: P2O5, CaO, MgO, Al2O2, Fe2O3, SiO2, SO4, SO3, F-. Easy to Use – apply with dosing pump as concentrated or pre diluted in water. Freeze Resistant – Pour point below (-) 10 Celsius

In many phosphoric acid plants, the primary rate limiting factor to improving phosphoric acid production rates is the ability to vacuum filter sufficient volumes of acid through the calcium sulfate cake on the plant filter. Metalub offers filtration aids to improve filtration and increase production rates and recovery. Metalub additives modify the size and shape of gypsum crystals, hence directly impact filtration rates, which in turn, influence production rates. Metalub technical department work closely with our customers to offer optimal work scheme. Metalub filtration aids offer the below benefits: Improved plant production rates. Improved overall P2O5 recovery. lower total organic carbon (TOC). Reduced defoamer usage in reactor
