Sustainable mining – oxymoron or a way of the future?

Mining is an activity that has persisted since the start of humans using tools. However, one might argue that digging a big hole in the ground and selling the finite resources that come out of that hole is not sustainable, especially when the digging involves the use of other finite resources (i.e. fuels) and produces a lot of greenhouse gases.

The counter argument could go along the lines that minerals are not being lost or destroyed through mining and mineral processing – the elements are being shifted around, and converted into new forms. Metals can even be extracted from waste, seawater or even sewage, and recycled. But a more simple argument is possible: a mine can be sustainable if it is economically, socially and environmentally beneficial in the short and long term. To be sustainable, the positive benefits of mining should outweigh any negative impacts. […]

Social positives are often associated with mines in regional areas, such as providing better amenities in a nearby town, or providing employment (an economic and social positive). Social negatives can also occur, such as dust, noise, traffic and visual amenity. These are commonly debated and, whilst sometimes controversial, can be managed with sufficient corporate commitment, stakeholder engagement, and enough time to work through the issues. Time is the key parameter - it may take several years for a respectful process of community input, but as long as it is possible for social negatives to be outweighed by social positives, then the project will be socially sustainable.

It is most likely that a mine development will have some environmental negatives, such as direct impacts on flora and fauna through clearing of vegetation and habitat within the mine footprint. Some mines will have impacts which extend beyond the mine site, such as disruption to groundwater, production of silt and disposal of waste. Certainly these impacts will need to be managed throughout the mine life, along with robust rehabilitation and closure planning. […]

The real turning point will come when mining companies go beyond environmental compliance to create 'heritage projects' that can enhance the environmental or social benefits in a substantial way – by more than the environmental offsets needed just to make up for the negatives created by the mine. In order to foster these innovative mining heritage projects we need to promote 'sustainability assessments' - not just 'environmental assessments'. This will lead to a more mature appreciation of the whole system whereby the economic and social factors, as well as environmental factors, are considered in a holistic manner.

Innovation is the new key to survival

[…]

At its most basic, innovation presents an optimal strategy for controlling costs. Companies that have invested in such technologies as remote mining, autonomous equipment and driverless trucks and trains have reduced expenses by orders of magnitude, while simultaneously driving up productivity.

Yet, gazing towards the horizon, it is rapidly becoming clear that innovation can do much more than reduce capital intensity. Approached strategically, it also has the power to reduce people and energy intensity, while increasing mining intensity.

Capturing the learnings 

The key is to think of innovation as much more than research and development (R&D) around particular processes or technologies. Companies can, in fact, innovate in multiple ways, such as leveraging supplier knowledge around specific operational challenges, redefining their participation in the energy value chain or finding new ways to engage and partner with major stakeholders and constituencies.

To reap these rewards, however, mining companies must overcome their traditionally conservative tendencies. In many cases, miners struggle to adopt technologies proven to work at other mining companies, let alone those from other industries. As a result, innovation becomes less of a technology problem and more of an adoption problem.

By breaking this mindset, mining companies can free themselves to adapt practical applications that already exist in other industries and apply them to fit their current needs. For instance, the tunnel boring machines used by civil engineers to excavate the Chunnel can vastly reduce miners' reliance on explosives. Until recently, those machines were too large to apply in a mining setting. Some innovators, however, are now incorporating the underlying technology to build smaller machines—effectively adapting mature solutions from other industries to realize more rapid results. 

Re-imagining the future

At the same time, innovation mandates companies to think in entirely new ways. Traditionally, for instance, miners have focused on extracting higher grades and achieving faster throughput by optimizing the pit, schedule, product mix and logistics. A truly innovative mindset, however, will see them adopt an entirely new design paradigm that leverages new information, mining and energy technologies to maximize value. […]

Approached in this way, innovation can drive more than cost reduction. It can help mining companies mitigate and manage risks, strengthen business models and foster more effective community and government relations. It can help mining services companies enhance their value to the industry by developing new products and services. Longer-term, it can even position organizations to move the needle on such endemic issues as corporate social responsibility, environmental performance and sustainability.

SAINT PATRICK'S DAY



    Saint Patrick's Day, also known as The Feast of Saint Patrick, is a traditional holiday celebrated every year on March 17th, the day the patron saint of Ireland, Saint Patrick, died. 

      Patrick, who was born in the fourth century, lived in the British Isles, a land that had been invaded and conquered first by the Romans and then by Germanic tribes. At the age of 16, Patrick was captured and taken as a slave from the British Isles to what is now Ireland. He lived there for several years herding sheep. He was a religious boy, and he prayed that he would someday return to his homeland.

     Legend has it that one night while he was praying, a voice told him to escape from the farm, and find a ship that was waiting for him in a harbor two hundred miles aways. Patrick got to the ship, sailed to Europe, and disembarked in what is now probably France. He ---1--- several of the ship's crew through a dangerous forest, praying all the time. Neither Patrick nor any member of his crew was captured. When some of the men were about to die of starvation, wild animals appeared to them to eat. Events such as these appeared to be miracles and gave rise to later legends surrounding Patrick.

    Finally finding his way home, Patrick felt that he was called by God to perform an important mission. He believed it was his duty to go back to Ireland and convert the Celtic people to the Christian Religion.

      Patrick arrived in England and became a missionary, traveling from village to village and talking about his faith. Once, several members of a tribe approached Patrick and told him that they found it difficult to understand and believe in the Holy Trinity. Patrick thought a moment, then stooped down and picked one of the plentiful shamrocks growing wild around Ireland. “Here are three leaves", he said, “yet it is one plant. Imagine the Father, Son and the Holy Spirit as each of these leaves. Here they are, yet they are one plant." The tribesmen understood, because Patrick had used a familiar object to explain. From that time on, the shamrock has been a revered symbol of Ireland.

    There are lots of stories about Patrick. One of them is about him forcing snakes out of the entire country of Ireland. Even though there are many different stories about how he accomplished such a task, it is probably not true. Patrick died on March 17th, and the Irish people set aside the day to mourn. He became the patron saint of Ireland. Mourning turned to commemorating him and celebrating his life. 

    Because of Saint Patrick, lots of cities around the world with a large population of Irish have parades. Green is one of the national colors of Ireland. Green stripes are painted on the streets where the parade will travel. People wear green shirts, ties, hair ribbons, and hats. There are even pubs which serve green beer on that day. 

   Saint Patrick's Day was made an official Christian holiday in the early seventeenth century. It is now observed by the Catholic Church, the Anglican Communion, the Eastern Orthodox Church and Lutheran Church. The day commemorates Saint Patrick and the arrival of Christianity in Ireland. Not only that, but it also celebrates the heritage and culture of the Irish in general.
