Akzo Nobel

AKZO NOBEL
Akzo Nobel Surface Chemistry AB, SE-444 85 Stenungsund, Sweden

We are at the forefront of the advanced colloid and surface chemistry upon which successful flotation depends. This has been achieved by over 50 years of research and development in molecular and surface chemistry, along with feedback from the field.

Our strengths - optimized solutions

The strength of our chemistry and process know-how lies in the fact that we customize solutions to fit each individual ore. And since the ore varies in composition, we must vary the process and adapt it to each individual case. These products cannot be found in a catalogue, they must be tailor-made in close cooperation with the customer.

There are other ores that would not, at present, benefit from a special flotation agent. Instead, the task is to find a standard flotation agent with the performance characteristics best suited to the ore in question.

Tailor-made or standard collectors - we approach each assignment individually assuming more the role of the customer’s partner than that of a traditional supplier.

For a sustainable future

Our focus is not only to provide highly efficient flotation reagents: it is equally important to focus on a sustainable future. We want and are able to support you with knowledge on the behavior and impact of our collector chemistry in your environment. We achieve this by performing a thorough risk assessment. We are also able to support you in other regulatory affairs. We are backed up by an experienced staff of toxicologists, a worldclass analytical department and last but not least, the experience of our team.

A wide range of applications

Successful flotation requires optimum interaction of all the components in the flotation process. The main role in this process is usually played by collectors. Collectors must, therefore, meet very high performance requirements.

Ideally, collectors should be;

  • Strong enough to enhance recovery but weak enough to enhance selectivity.
  • Able to provide a high rate of flotation and good froth.
  • Non-sensitive to variations in the composition of the ore and the quality of the water.
  • Designed to meet environmental requirements.
  • Easy to ship, store and handle.
  • Cost effective.

We can help improve your enrichment rates if you work with any of the following minerals:

  • Apatite/phosphate
  • Barite
  • Calcite
  • Dephosphorization
  • Dolomite
  • Feldspar
  • Fluorspar
  • Graphite
  • Iron ore
  • Kyanite
  • Magnesite
  • Monazite
  • Potash
  • Pyrochlore
  • Quartz
  • Scheelite
  • Silica
  • Wollastonite
  • Zinc oxides

Cheminova A/S

CHEMINOVA A/S
Thyboroenvej 76-78, DK-7673 Harbooere, Denmark

Cheminova A/S - your reliable supplier of dithiophosphate collectors

  • Global player
  • Export to more than 100 countries
  • World leader with 50+ years of experience producing organo-phosphorous compounds
  • In-house specialized staff to ensure efficient distribution of chemicals worldwide
  • Supply products of the highest quality in the market

DanafloatTM Collectors

Cheminova’s dithiophosphate collectors are marketed globally under the brand name DanafloatTM. In addition, Cheminova sells other types of flotation agents to offer a broad product line for froth flotation to the mining industry. DanafloatTM product lists by ore type and by product available on www.cheminova.com \Business Areas\Other Products\Flotation Agents.

Production

Through its almost 70-year history Cheminova has grown into the largest basic manufacturer of organo-phosphorous compounds, including dithiophosphate flotation reagents, competitive due to the economics of scale in purchasing and production. Cheminova uses the latest process technologies and methods including continuous processes. Our in-house process development and improvement capabilities are two of our company’s core competitive strengths.

To control our product quality and costs, Cheminova has vertically integrated our chemical production. Cheminova converts elemental phosphorus and sulphur into phosphorus pentasulfide at the largest such plant in Europe. Selected alcohols are then reacted with the phosphorus pentasulfide to flotation dithiophosphate reagents as acid products and liquid solutions neutralized with sodium, potassium or ammonium hydroxide. Due to Cheminova’s process flexibility, products can be tailored to our customers’ process requirements. Cheminova can supply from less than one ton up to several thousand tons of a product.

Logistics

Cheminova has long experience in distributing products to more than 100 countries around the world. A logistical system is always designed in co-operation with the customer depending on the importance of different factors, such as speed, cost, safety, packaging, etc.

In addition, our extensive experience in packaging and labelling ensures the highest standards for product delivery and environmental compliance. Safety during transport is of particular importance to us.

It is our belief that our logistical flexibility provides our customers with a competitive advantage.

Service & technical support

Cheminova field and laboratory technical services personnel support customer design of a flotation reagent suite needed to maximize mineral recovery for each ore. Resultant reagents can include the industry’s widest range of dithiophosphates, thionocarbamates, mercaptobenzothiazole and possibly specifically designed chemistries for your application. Additionally, product blends may be supplied depending on the metallurgical requirements for a specific ore.

Quality products, long experience and technical plus logistics support makes Cheminova an attractive partner to the mining industry.
