Florrea HX series Flocculant

Trade Name: Florrea HX4, HX6, H6A, HX36, HX47 Flocculant

Introduction
Bauxite mines and alumina refineries strive to maximize liquor productivity and operating efficiency while minimizing
environmental impact around the world. Much of this effort is focused on optimizing the Bayer process to increase
precipitation yield, improve product quality, reduce energy and water consumption, and minimize red mud disposal
and storage. This requires a specialty chemical partner with a deep understanding of liquor and aluminum oxide
chemistry and a robust portfolio of process aids designed specifically for bauxite mines and alumina producers.

FLORREA brings together a unique combination of expertise, innovative products and analytical tools. Our field
professionals will work closely with your refinery personnel to audit your operating conditions, identify opportunities
to increase process efficiency and recommend the right chemicals and equipment to improve the entire production
cycle, on both the red and white side. It is Tailored Solutions for the Bayer Process and Alumina Refining

FLORREA flocculants HX6, HX6A, HX36, HX4 and HX47 are emulsion-based product for use in alumina plants to settle
red mud slurries.
They are high-performance flocculants for liquid/solids separations and selective flocculation.
These products provide better separations, fast settling rates and clearer overflows across a wide range of mineral
processing applications – resulting in increased throughput and product recovery.

 

Product Functions
  •  Flocculant To Aid Settling
  •  High Efficiency
  •  High Settling Rate
  •  High Stability
  •  High Throughput
  •  Improves Settler Overflow Clarity
  •  Suitable For Hard-to-treat bauxite

 

Principal Uses
FLORREA HX series flocculant was specifically developed for high performance settling and clarification of digester blow-off slurry and thickening of washed red mud. It has shown the response of good settling and
compaction, commensurate with excellent clarities in several alumina operations.

Application
FLORREA HX series flocculant is dissolved in condensate or weak solids free liquor (5-20g/l NaOH) to make a stock solution. The stock solution is further diluted and mixed with decanter feed via dual addition. .A portion of the solution is added into the feed line and the rest into the feedwell.

Preparation of Stock Solutions
FLORREA HX series flocculant should be thoroughly mixed in the storage container prior to initial use. A tank mixer should be run for about 30 minutes to ensure preparation of smooth, uniform product.

Handling and Storage
FLORREA HX series flocculant should be stored at temperatures between 5-30°C. Do not allow the product to freeze. Avoid the use of aluminum, copper, iron or mild steel in storage systems. Storage in glass, stainless steel, plastic or epoxy-lined containers is recommended.
