Zinc Sulphate Heptahydrate 99% - 102%

ZINC SULPHATE Heptahydrate 

99% - 102%

Zinc Sulphate Heptahydrate (ZnSO₄·7H₂O) is an inorganic compound appearing as colorless, crystalline granules or powder with a slightly astringent taste. It is highly soluble in water and widely used in various industrial and agricultural applications. As a technical grade material, this product is formulated for non-food applications where high purity is not critical but reliability and consistency are important.

Uses:

1. Agriculture:

   • Used as a zinc micronutrient fertilizer to correct zinc deficiency in crops and soil.

   • Ingredient in foliar sprays and soil applications to boost plant health and growth.

2. Industrial Applications:

   • Utilized in the manufacturing of rayon, zinc salts, and lithopone.

   • Employed in electroplating and as a mordant in dyeing.

3. Water Treatment:

   • Acts as an algaecide and flocculant in water purification processes.

4. Animal Feed (with caution):

   • Occasionally used in technical formulations for animal nutrition (usually with further refinement).

5. Mining and Metallurgy:

   • Used in flotation processes in mining to separate valuable minerals.

Frequently Asked Questions (FAQ):

Q1: What is the difference between technical grade and food/pharmaceutical grade zinc sulphate?

A: Technical grade zinc sulphate is intended for industrial or agricultural use where ultra-high purity is not essential. Food and pharma grades undergo stricter purification and testing processes to ensure safety for human consumption.

Q2: Is Zinc Sulphate Heptahydrate safe for plants?

A: Yes, when used as directed, it is beneficial for plant growth, especially in zinc-deficient soils. Overuse, however, can lead to soil toxicity—always follow recommended agricultural guidelines.

Q3: How should Zinc Sulphate Heptahydrate be stored?

A: Store in a cool, dry place in a tightly sealed container. Keep away from moisture and incompatible materials like strong acids and alkalis.

Q4: Can it be used in animal feed?

A: While zinc is an essential nutrient for animals, technical grade zinc sulphate is not recommended for direct inclusion in animal feed without further purification. Use feed-grade zinc sulphate for such applications.

Q5: What precautions should be taken during handling?

A: Use personal protective equipment such as gloves, goggles, and masks. Avoid inhalation and direct skin contact. Work in a well-ventilated area and follow proper industrial hygiene practices.
