In addition to our flotation and hydrometallurgy range, A S Harrison & Co offer a large number of modifying agents that are commonly used in the flotation of sulfide ores.
Hydrated lime is used commonly to adjust pH for maximum recovery and selectivity for a given collector. Inorganic depressants such as sodium cyanide and sodium metabisulphite are used to depress iron sulfide minerals such as pyrite, pyrrhotite and arsenopyrite and Zn minerals during Pb flotation from Pb/Zn ores and Zn sulphide (sphalerite) and Fe sulphide (e.g. pyrite, pyrrhotite) minerals, respectively.
We offer a range of flotation collectors that afford surface modification (increased hydrophobicity) of minerals. Based on their chemical compositions and affinities, some flotation collectors will tend to be attracted to one mineral more than another.
Depression of silicate gangue (e.g. talc, serpentine, lizardite, antigorite) may be afforded with the use of guar gum.

Product and customer insights
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 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.
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.
Keeping drilling costs low using Redi-Guard™ High Performance, an ecologically friendly drilling fluid technology with revolutionary rheological and shale encapsulation properties
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.
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.
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.
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.
