Acid mist suppressing agents are crucial in the electrowinning process, effectively mitigating the formation of harmful acid mist, thereby enhancing safety and equipment durability. In electrowinning cells, oxygen bubbles form on the anode. When these bubbles burst at the solution/air interface, they produce fine acid droplets known as acid mist. This mist is highly corrosive, posing significant health risks to operators and causing severe damage to the structural integrity and equipment within the tankhouse.
The primary benefit of acid mist suppressants is their ability to substantially reduce acid mist generation. By coating the solution’s surface and stabilising oxygen bubbles, these agents prevent the rapid bursting of bubbles, thereby minimising the formation of fine acid droplets. This reduction significantly improves the working environment by decreasing airborne acid particles, thus lowering the risk of respiratory and dermal health issues among personnel.
Moreover, these agents enhance the morphology of the cathode. In electrowinning, acid mist can adversely affect the surface quality of the cathode, leading to irregularities and uneven deposits. Acid mist suppressant agents act as smoothing agents, promoting uniform deposition of the cathode material. This enhancement ensures consistent and high-quality cathode surfaces, crucial for optimal electrical conductivity and the quality of the final metal product.
Additionally, acid mist suppressant agents help prolong the lifespan of equipment and structural components within the tankhouse. By reducing the corrosive impact of acid mist, these agents prevent extensive damage to metal surfaces, piping, and other infrastructure. This protection reduces maintenance costs and downtime, enhancing operational efficiency and supporting a safer and more sustainable working environment.
Acid mist suppressant agents are indispensable in the mining industry. They provide critical benefits by reducing health hazards, improving cathode morphology, and protecting equipment from corrosive damage, thereby enhancing the overall efficiency and safety of electrowinning operations.

Product and customer insights
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 […]
Keeping drilling costs low using Redi-Guard™ High Performance, an ecologically friendly drilling fluid technology with revolutionary rheological and shale encapsulation properties
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
silica polymerization and that even while the ferric hydroxide was removed, the silica scaling was continuing to grow.
The East Hokkaido region is known to have the highest volume of potato product in Japan. Unfortunately, a potato farmer in the area was experiencing a high rate of potato scab infection in his agricultural field.
