Zinc.
The protector of infrastructure.

One of the most produced metals in the world, used mainly to galvanize steel against corrosion, as well as in batteries, alloys and industrial chemistry. Zinc deposits and tailings are usually polymetallic, with lead, silver and copper.

Industrial uses

What zinc is used for, today.

Stable-volume demand, elastic in value. Growing in zinc-air batteries and public health applications.

~50% of demand

Steel galvanization

Zinc-coated steel — in sheets, pipes, structural profiles, vehicle bodies. Low-cost anticorrosive protection, century-old tech, scalable. Backbone of modern infrastructure.

~17% of demand

Metal alloys

Brass (Cu + Zn), bronze (with copper), zamak (die-casting alloy). Applications in technical parts, valves, electrical accessories, cast automotive components.

Growing segment

Batteries

Alkaline, zinc-carbon cells. Emerging: zinc-air batteries for stationary energy storage, alternative to lithium-ion for grid applications.

Health

Pharmaceutical and nutrition

Supplements, sunscreens (zinc oxide), antiseptics, dermatological protectors. Essential immune nutrient.

Chemical

Pigments and chemicals

Zinc oxide in rubber (tires), ceramics, white pigments. Zinc sulfate as soil fertilizer in large-scale agriculture.

Agricultural

Fertilizer and crop protection

Correcting zinc deficiency in large-scale soils — especially cereals. Low dosage, high impact on agricultural productivity.

In mining

Older polymetallic assets.

Zinc deposits are rarely monometallic: zinc occurs with lead, silver, copper and sometimes cadmium or indium. Older operations often focused on the highest-value metal of the time, and the others went to tailings.

With changes in prices and technology, some of these materials are being evaluated again. The potential of each asset depends on the set of metals present, the mineralogy and the project conditions.

How Green Mining assesses

The value is in the combination.

For polymetallic streams, the assessment considers the combined value of the metals present and the constraints of each, such as contaminants and concentrate specifications. Zinc alone may not justify a project; combined with other metals, it sometimes does.
