Cheminova was established in Copenhagen by Mr. Gunnar Andreasen, a chemical engineer, in 1938.The company has grown to become an important manufacturer of plant protection chemicals, chemical intermediates, and flotation chemicals.In 1953 Cheminova moved our manufacturing plant to its present western Jutland location on the Rønland peninsula between the North Sea and the Liim Fiord. Because elemental phosphorus and sulphur raw materials are delivered directly to the plant, Cheminova’s manufacturing is completely vertically integrated and provides Cheminova considerable infrastructural advantages, which have been an important factor in Cheminova’s growth. Additionally the location enhances ourability to effectively manage our costs, final product qualityand responsiveness to our customers.
Cheminova has become a well-established leader in the production of organophosphate reagents and chemicals with the portfolio now including:
• Mineral flotation reagents
The flotation chemical product line is a very important product line extension to our agricultural chemicals because the dithiophosphate phosphorus-sulphur chemistries are quite complementary to the agriculture chemicals, which are also phosphorus and sulphur based.
Cheminova uses the latest process technologies, process flowsheets and methods that maximize process control in producing the industry’s leading quality products and to effectively manage production costs, particularly our mining flotation reagent line. All our products are produced in ‘reactor trains’,which is a series of reaction vessels that are monitored and controlled by the latest computer technologies.
The continuous production processes, which are closely supervised by operators to maintain constant production flow and consistently high product quality,are state of the art. Well trained and competent personnel operate these plants. Cheminova’s operators must complete a full two-year training programme before being allowed to independently operate the plant. The result: industry leading quality products that have the highest activity levels with minimum unreacted raw materials and reaction by-products versus competition. The high capability of our production plant is are flection of Cheminova’s manufacturing competence.
Our production is based on utilization of bulk commodity raw materials. This reduces costs and increases supply independence to the benefit of our customers and business partners.Cheminova converts elemental phosphorus and sulphur intophosphorus pentasulfide at the largest such plant in Europe. Selected alcohols are then reacted with the phosphorus pentasulfideto provide the various phoshorodithioic acids and saltsolution products.
A wide range of flotation dithiophosphate reagents are produced in acid and aqueous solution forms, the latter using sodium, potassium or ammonium hydroxide for neutralization. To ensure our products provide the best possible mineral processing circuit performance, we have developed dithiophosphate mixtures and mixtures of dithiophosphates with mercaptobenzothiazole and thionocarbamates that have been developed and tailored for the rigorous needs of the mining industry. Due to Cheminova’s process flexibility, products can be tailored to our customers’ process requirements.
In order to provide a full complement of flotation reagent products, Cheminova also supplies some frothers.
