Episode 12 | Women in Mining

✅ The Mining Experience is a live podcast that invites professionals from the mining industry to discuss new technologies, address challenges, and share work experiences.

In this episode, we had the honor to have 2 amazing women sharing their experiences in the mining industry.
We talked about the difficulties of being part of an industry that is largely male-dominated, why it is vital that women’s voice is heard for the mining sector to improve in equity, diversity and inclusion. We consider it is everyone’s responsibility to work for a transformation that benefits employees, communities, businesses and organizations.

Ours special guests for this episode were:
👷🏼‍♀️Eva Dierkes
Eva, has a master’s degree in mining engineering from Germany. After moving to Canada she worked for a few years as a QC specialist in the video game industry. She joined Promine nearly 5 years ago as a QA specialist and has since then become the VP of Technical Services.

👷🏻‍♀️Rim Kouider
Rim is a junior mining engineer who graduated from McGill University. Throughout her internships, she acquired a diversified experience in material handling, process, drill & blast, and project management. She worked with Rio Tinto in project management and controls and has now joined Tetra Tech as a junior engineering consultant. Additionally, she studies management of the mineral industry and is highly involved in the student community. She helped organize the 32d edition of the Canadian Mining Games and will stay on the team as part of the Board of Directors.​

Episode 11 | Effective Mining Workflows | The Mining Experience

✅ The Mining Experience is a live podcast that invites professionals from the mining industry to discuss new technologies, address challenges, and share work experiences.

In this episode, we discussed Effective Mining Workflows. Our hosts and guest talked about different methodologies on how to perform organization to stay efficient and consistent in a project, whether it’s for mining or any other type of process. Doing so can also ensure that your whole team is up-to-date on all aspects of a certain process, allowing a better coordination.

This episode had the honor to invite a very special guest:

➡️ Pedro Gamboa; Pedro is Geologist and a mining specialist. Currently, he works as a Project Manager for the Consulting Department at Promine Inc. Leader of a group of geologists, him and his team provide support to mining sites in the digital acquisition of databases, records and plans. With a background of more than 14 years teaching CAD Systems, GIS, Basic Programming, Database Manipulation, as well as interaction with Operating Systems and Office Automation, he previously obtained the position of Associate Professor, and the Department Chair of Civil Engineering at the Universidad de Oriente in Venezuela. In addition, he performed academic research collaborations with A.C.

The importance of predicting dilution

The importance of predicting dilution

In a globally competitive market such as the mining sector, dilution estimation plays one of the most important roles, directly affecting the economy of the different projects. However, to understand why this estimation is so important, let’s first define the term technically.

Dilution is defined as the ore contamination throughout the mining process by the waste or material that is below the cutoff grade, hindering sometimes the recovery process, and thus increasing the waste volume. Dilution can be either planned or unplanned. Planned dilution refers to the waste or sterile that lies within the designed stope boundaries, while unplanned dilution alludes to the waste derived from the backfill outside the stope boundaries. (Clark, 1998)

According to Ebrahimi (2013) “it is common to assume a general dilution such as 5% for massive deposits and 10% for tabular shape deposits”, nevertheless, it is important to consider the features of each deposit that can affect the ore extraction altering the dilution percentage, consequently, affecting the extraction costs. Some of these features are:

  • Mining method.
  • Orebody shape.
  • Drill and blasting techniques.
  • Instability of the stope wall.
  • Equipment size.

However, the dilution does not only generate an economic impact, but it has also been demonstrated that has a direct impact on the increase of the ecological footprint in mining operations. This is due to the dilution underestimation, because if calculations are not accurate more material can be considered as waste, which subsequently, must be stored in a tailings pond on the surface and without an adequate treatment, acid mine drainage can be caused.

Therefore, an action plan for dilution control must identify in first instance the dilution source, to be able to predict and control it with the appropriate tools, thus significantly reduce the mining losses and increase the profitability of mining operations.
