Dispersing agents are vital in mining operations, playing a crucial role in improving the efficiency of mineral processing. These agents help in the separation of valuable minerals from gangue materials, ensuring higher yields and better-quality concentrates. Our series of strong dispersant esters are particularly effective in this regard, offering advanced solutions for various mining applications.
Strong Dispersant Esters
Our versatile esters are specially formulated to provide superior performance in mineral processing. These esters are nonionic, anionic, and cationic polymers designed to depress gangue in flotation processes. They work by selectively dispersing unwanted materials, allowing for the preferential flotation of valuable minerals. This selectivity is essential for the efficient processing of ores containing nickel, gold, lead-zinc, copper, iron, and industrial minerals. By ensuring that valuable minerals are separated from gangue, these dispersant esters enhance the overall efficiency and profitability of mining operations.
Depression of Gangue in Flotation
Dispersants are essential for the depression of gangue materials in flotation processes. Low and intermediate molecular weight polymers are specifically designed to depress iron sulfides and maintain low viscosity. These agents effectively disperse slimes, clays, and silicates, preventing them from interfering with the flotation of valuable minerals. This ensures that the flotation process is more efficient, resulting in higher yields and better-quality concentrates.
Maintaining Low Viscosity
One of the key benefits of using dispersing agents in mining is their ability to maintain low viscosity in mineral slurries. High viscosity can hinder the separation process, reducing the efficiency of mineral recovery. Dispersing agents help to keep the slurry fluid, allowing for easier handling and more efficient separation of valuable minerals from gangue materials. This is particularly important in the processing of ores with high clay content, where maintaining low viscosity is crucial for optimal performance.
Selective Dispersion for Preferential Flotation
Our dispersing agents are designed to be highly selective, ensuring preferential flotation where required. This selectivity is critical for the efficient processing of complex ores, where different minerals need to be separated with high precision. By using dispersing agents that are tailored for specific mineral types, mining operations can achieve better separation efficiency, leading to higher-quality concentrates and improved overall productivity.
Versatile Applications in Mineral Processing
Dispersing agents are used across a wide range of mineral processing applications, including the flotation of nickel, gold, lead-zinc, copper, iron, and industrial minerals. Their versatility and effectiveness make them indispensable in modern mining operations. By incorporating strong dispersant esters into their processing strategies, mining companies can enhance their operational efficiency, reduce processing costs, and achieve higher yields.
Dispersants are essential for optimising mining operations. Their ability to depress gangue materials, maintain low viscosity, and ensure selective dispersion makes them invaluable for the efficient processing of various ores. By leveraging these advanced solutions, mining companies can significantly improve their productivity and profitability.

CHALLENGE A 40-hectare raw water storage dam had persistent issues with blue-green algae (BGA) blooms, leading to taste and odor problems. Despite the presence of an aeration system to address water stratification and mixing, BGA counts remained seasonally high, particularly in summer and autumn. Upgraded aeration in 2018 did not resolve the issue, leaving the […]
The International Maritime Organisation (IMO) regulation, known as IMO 2020 was the the largest change in regulation relating to marine fuels impacting 75% of the fuel used by the shipping industry.
CHALLENGE A power plant relying on ultrafiltration (UF) and reverse osmosis (RO) faced a critical operational challenge. A wastewater treatment upset severely fouled the UF system, drastically reducing water production. Despite multiple cleaning attempts with sodium hypochlorite and citric acid, transmembrane pressure (TMP) remained high, and flux showed no improvement. The plant’s inability to meet […]

CHALLENGE A municipal water reuse plant processing 8 million gallons per day (MGD) experienced severe fouling and scaling issues, including calcium phosphate and silica deposits. With steep feed pressure increases and differential pressures in both stages, the plant required frequent cleanings every 4 to 6 weeks, amounting to 32 cleanings annually. Each cleaning cycle resulted […]
The plant was experiencing weekly shutdowns for fiber clean up (~ 3 kg bags of matted slurry is cleaned per week). The shut downs were costly as they reduce plant availability for production.
CHALLENGE A municipal reverse osmosis (RO) plant on Florida’s west coast, with a 20 MGD capacity, faced high operational costs due to its reliance on 93% sulfuric acid for pH adjustment. The plant used a combination of a brackish water reverse osmosis (BWRO) membranes and fiberglass-wrapped membranes across 10 trains, each operating at 75% recovery. […]
CHALLENGE A gold processing plant in New Zealand sought to improve gold recovery efficiency while addressing high Total Organic Carbon (TOC) levels. Elevated TOC increased the Preg-Robbing Factor (PRF), reducing the plant’s ability to efficiently recover gold during the Carbon-In-Leach (CIL) process. The traditional use of kerosene as a carbon blanking agent offered limited efficacy, […]
CHALLENGE A municipal reverse osmosis (RO) plant, with a capacity of 2 million gallons per day (MGD), faced frequent system cleanings, every 2-4 months, due to rising feed pressure. The plant, which sources water from brackish wells and uses Toray TMG-20D-400 membranes in a (16×7) -> (8×7) train configuration, was operating at 78% recovery. Despite […]
Research indicates that Sea Buckthorn may be able to strengthen the immune system. One in vitro study focused on the possible immunomodulatory properties of Sea Buckthorn.
AWC A-110 effectively inhibited scale at a dosage of 3.5 ppm and an operating pH of 6.9. This increase in operating pH reduced the district’s annual acid consumption by ~$350K per year based on their current production.
MCI® -2020 V/O and ChemMaster’s Colorsil were chosen to repair and protect the walls based on their 20 year warranties and the fact that together they could fulfill the other specified repair design requirements.
Despite numerous cleanings, the productivity of the Reverse Osmosis plant would not recover from severe membrane fouling. The membrane autopsy revealed that the ferric hydroxide was seeding
