H. The industry has submitted letters issued by the DTP, Ludhiana, vide no. 371 dated 22.02.2022 and no. 3039 dated 19.11.2025, confirming that the site of the industry falls within the industrial zone as per the Master Plan, Ludhiana (2007–31).
I. The industry has submitted a project report along with the feasibility report for its proposed expansion, the details of which are as follows:-
a. The existing manufacturing process flow for zinc sulphate monohydrate shall be carried out as follows: Preparation of Raw Materials (Zinc Ash/ Dust/ Skimmings, Sulphuric Acid (Strength 98%) & Water), Leaching, dissolution, filtration, crystallization, drying, inspection, packing for dispatch.
b. The proposed manufacturing process flow for Ferrous Sulphate shall be carried out as follows: Preparation of Raw Materials (Iron Slag/ Ash/ Dust/ Powder, Sulphuric Acid (Strength 98%) & Water), Leaching, filtration, crystallization, drying, inspection, packing for dispatch.
c. The proposed manufacturing process flow for zinc shall be carried out as follows: Preparation of Raw Materials (APCD flue gas dust, Ammonium Chloride, Calcium Chloride, Hydrogen Peroxide 50%, Water), leaching, purification, electrolysis, packing, ready for dispatch.
d. The proposed manufacturing process flow for zinc oxide shall be carried out as follows: Preparation of Raw Materials (Zinc Hydroxide & Zinc Carbonate), calcination (In High temperatures), collection as fine powder, packing, ready for dispatch.
J. The total fresh water requirement for the project will be 16.075 KLD, which will be
abstracted from a submersible pump within the industry’s premises.
