The Mining Lab Challenge program was created to support initiatives of entrepreneurs who wish to develop technological innovation projects for the mining and metallurgy industry.

Initiatives of entrepreneurs around the world will be identified and connected, so they receive an equity-free investment, that is, an investment with no corporate counterpart.

Nexa aims at being a venture client, acting as a client of the initial producer instead of taking part in the capital of your company.

information for each challenge

Producing Zinc and Copper

The production begins with mineral exploration and then the ore mined is transported to the beneficiation process where the concentration occurs. This concentrate goes to the smelter where it is refined and melted, thus producing metallic zinc and copper, zinc oxide and by-products.

We seek innovative solutions and technologies that can be tested in a proof of concept up to 12 months, involving scientific aspects and that are capable of transforming and increasing our production chain.

The focus on this challenge is divided into:
- Mining and Beneficiation
- Refining and Smelting

Check out Nexa's needs in this challenge:

  • Lead sulfate flotation (Mining and Beneficiation)
  • New coatings for electrolysis cell (Refining and Smelting)
  • Separation of manganese dioxide in the exhausted solution of electrolysis (Refining and Smelting)
Applications closed

Management and Elimination of Tailings and Effluents

During the beneficiation, process tailings are generated, which are destined for deposits and, at the refinery, when processing the concentrate, waste is generated. In addition to these, there are energetic residues, which must be reused, gaseous emissions and liquid effluents.

We seek innovative solutions and technologies that can be proven in up to 12 months and that are capable of transforming and increasing our management process, eliminating waste and effluents and transforming them into new products.

The focus on this challenge is divided into:
- Tailings
- Effluents

Check out Nexa's needs in this challenge:

  • Development of new process routes or new business models for the use of Pyrite (Tailings)
  • Development of new products from Jarosite (Tailings)
  • System for managing atmospheric emissions and air quality (effluents)
Applications closed

Developing Positive Legacies

Nexa's operations have a finite operating life and, after the closure activities, the benefits generated will cease to exist. It is in our interest to have a set of complementary actions for future use , both in short and long terms, as well as structuring actions that generate positive cash flow in these locations for an indefinite period.

We seek to create a network that promotes the sustainable economic development of these territories by developing their local resources and bringing qualification to the workforce, expanding the possibilities of employment generation and income

The focus on this challenge is divided into:
- Encourage local entrepreneurship
- Future use with new business models

Applications closed

Greater Efficiency and Productivity

The core of Nexa is zinc and copper. However, we have a structure that must remain organized. Areas such as engineering, OSH, human development, among others, seek innovations that increase their productivity, enhance their connection, rationalize the resources allocation and manage risk exposure. In addition and aiming to accelerate our transformation, we seek to automate and stabilize our industrial processes.

We look for innovative solutions and technologies that can be proven in up to 6 months and that are capable of developing our activities.

The focus on this challenge is divided into:
- Productivity
- Digitalization
- Industrial automation

Check out Nexa's needs in this challenge:

  • Team management tools in different work regimes or units (productivity)
  • Estimation of gold contained in mineral resources through artificial intelligence (digitalization)
  • Robotic system for loading explosives (industrial automation)
  • Image analysis for dam slope control (industrial automation)
Applications closed
