By-products

Applied in several areas such as agriculture, livestock and chemical industry

By-products in practice

We use new technologies to develop products from our waste, thus preventing and reducing impacts on the environment. Our by-products line can be applied in several areas, such as agriculture, livestock and chemical industry.

Zinc oxide 72-75% and type C

The product is registered with the Ministry of Agriculture, Livestock and Supply (MAPA)/MAPA in Brazil, and is highly used in the production of fertilizers and sulfates. The color of zinc oxide 72-75% and Type C products can vary from yellowish to dark gray.

Copper sulfate

Copper sulfate is mainly used in agriculture, mining and in the chemical industry for electroplating processes in coatings and decorative finishes of metallic parts. This material is also registered with MAPA and complies with current regulatory provisions.

H2SO4 / SO2

Sulfuric acid (H2SO4) can be used in the production of fertilizers and sulfates, water treatment, leaching in the chemical industry, bleaching of paper, pulp and sugar. Sulfur dioxide (SO2) can be used in the bleaching process of paper, sugar and kaolin, in addition to being used as a preservative in food products and in the production of bisulfites.

Copper cement

Used in the production of copper sulfate, in the enrichment of copper concentrates and in the production of metallic copper. Copper cement has reddish material with a particle size 100% smaller than 75 μm or micron.

Silver concentrate

Raw material to produce metallic silver, the silver concentrate is a light brown particulate material, with a particle size 100% smaller than microns.

Cadmium/Sponge

Cadmium is a by-product of the zinc production process. The product is mainly used in the nickel-cadmium battery industry and in the manufacture of pigments, being traded in the form of high purity rods or metallic sponge.
