BUSINESS PLAN FOR PRODUCTION OF ZINC SULPHATE

Introduction
Zinc sulphate is a colorless crystalline, water-soluble chemical used to manufacture animal feeds,
fertilizers and agricultural sprays. Zinc sulphate checks weeds and protects against pests and diseases. It also has applications in textile dyeing and printing, as a reagent in glues, in electro galvanizing paints, varnishes and in the manufacture of many zinc compounds. Zinc sulphate has a good market potential in rural areas and agriculture sector. The business idea aims at production of 3,900 kgs of zinc sulphate per month. The revenue potential is estimated at 351,000 annually with a sales margin of 10%; the total capital investment for the project is 11,104 dollars.
 

Plant Capacity
The plant in this profile has a minimum capacity of 46,800 kgs of zinc sulphate per annum.

Production Process
Zinc sulphate is manufactured by leaching zinc ash with dilute sulpuric acid. The leached solution is filtered to separate un-reacted zinc, which is reused along with the next charge. The filtrate is treated with potassium permanganate and zinc dust to precipitate impurities. It is then treated with nitro so beta-naphthol to remove cobalt. The excess of sulphuric acid is neutralized with zinc carbonate. The solution is filtered and evaporated. After evaporation, the thick solution is allowed to settle in a settling tank where crystals of zinc sulphate come out of the cooler. The crystals are separated from the mother liquor in a centrifuge and dried on belt drier. The mother liquor is re-circulated to the evaporator. The crystals are then packed and marketed. 

 Market Analysis
There is market potential for Zinc since the Textile Industry which
is the main consumer is in its infancy stage. 

 

Production is assumed for 312 days per year.
Depreciation assumes 4 year life of assets written off at 25% per year for all
assets.
 

A production Month is assumed to have 26 work days.
