Copper mining waste storage piles may be as large as 1,000 acres and typically include three types of waste tailings, dump and heap leach wastes, and waste rock and overburden. The amount of marketable copper produced is small compared to the original material mined. Several hundred metric tons of ore must be handled for each metric ton of ...
To the east, miles in the distance, lays a broad valley, and within it a streak of dark greenthe willows and cottonwoods of Cienega Creek, which flows all year. This network of waters, at Las Cienegas National Conservation Area, provides a home to scarce animals including the Gila topminnow, a sparkly-silver, inch-long fish, and Gila chub, which are larger and more rotund. Yellow-billed cuckoos also roost here. These species, all endangered or threatened, thrive in this precious bit of desert water.
Above the valley loom the distant Whetstone mountainswhere, until as recently as the 1870s, Apache warriors hid out between raids on ranches in the Cienega Valley that era of bloodshed ended only when Geronimo and his renegades finally surrendered in 1886, forced onto reservations.
Dec 03, 2016nbsp018332Different types of mining have various impacts on land. For example, strip mining results in the clearing of trees, plants and topsoil 2. One effect of this type of mining on the environment is the pervasive problem of soil erosion, which in turn leads to the pollution of waterways.. Another destructive type of mining is underground coal mining.
Mar 09, 2017nbsp018332Mining is an inherently destructive industry, and the mining effects of even a single operation can have a severe impact on the environment and the wildlife that lives nearby. Although there are some regulations in place that are intended to minimize the damage, they are not enough to allow mining and wildlife to exist in harmony, especially in ...
That being said, this region does have a heart of sorts the Cienega Aquifer, below us, where water has collected for millennia. It flows through dozens of springs and into Cienega Creek, supporting a rich abundance of wildlife like deer and javelina, which attract the aforementioned jaguars and ocelots, as well as mountain lions and bobcats. Its one of only two mountain ranges in the United States where four wild cat species have been spotted recently.
The curved spine of the Santa Ritas moves south from here, connecting with the Patagonia Mountains and Mexican ranges south of that, forming a continuous rise of highlands. This connectivity allows mammals like jaguarswhich have a breeding population in northwest Mexicoand birds like elegant trogons to trek up from Central America. Many tropical species are thus found in southeastern Arizona and nowhere else in the U.S. This specific spot in the northern Santa Ritas also provides wildlife corridors to the Empire Mountains, Whetstones, and Rincons to the east and north.
Apr 25, 2017nbsp018332Environmental Impacts Of Mining. As mentioned previously, mining activities can harm the environment in several ways. These are as follows Air Pollution. Air quality is adversely affected by mining operations. Unrefined materials are released when mineral deposits are exposed on the surface through mining.
These tailings would cover miles of streams that lead into Davison Canyon, to the northeast. Runoff from the mine would run down the canyon, which eventually joins with Cienega Creek to flow into Pantano washa seasonal stream Ive explored since childhoodthat cuts straight through Tucson.

Apr 24, 2018nbsp018332Copper ore grade is down from 4 a century ago to well under 1 now and falling. Copper mining isnt just affected by natural resource pressures it
Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is ...
Feb 21, 2019nbsp018332Mining activities, including prospecting, exploration, construction, operation, maintenance, expansion, abandonment, decommissioning and repurposing of a mine can impact social and environmental systems in a range of positive and negative, and direct and indirect ways. Mining can yield a range of benefits to societies, but it may also cause conflict, not least in relation to above
In the early days of corporate environmentalism, the focus was mainly on big, heavy industries. Fossil fuels and mining had the most obvious environmental issues, as well as extensive regulatory regimes to navigate. These days, however, sustainability discussions are more often focused on the actions of consumer product, retail, and tech brands. But its important to check in periodically with the big guns of environmental impact and see how theyre thinking about these issues.
Thus, it was with real interest that I recently found myself in Chile visiting the World Copper Congress, where I spoke at a dinner for 1,800 executives held by the Center for Copper and Mining Studies CESCO. There, it became clear to me that the modern sustainability agendanbsp beyond regulatory compliancenbsp is becoming critical to this sector, with both risks and opportunities stemming from environmental and social pressures.
For context, consider the scale of copper, with upwards of 25 million tons produced annually. Chile is the biggest source, producing about 25 of the global total. And the biggest buyer is China, which sent a sizable delegation. China uses roughly 40 to 60 of the worlds major commodities, including, as the Chairman of CECSO told me, about 45 of global copper.
Lets start with the risks. A world growing to 9 or 10 billion people, with many getting richer, needs more of everything. But the richness of ores the ore grade has been in long-run decline for most elements. Copper ore grade is down from 4 a century ago to well under 1 now and falling. Copper mining isnt just affected by natural resource pressures it embodies natural resource constraints.
Second, the rise of the clean economy is creating new, exciting growth markets for copper. A The rapid drop in the cost of battery storage is driving some rosy projections for the use of electric vehicles EVs. And EVs need a lot of copper. A pure EV requires roughly 4 times as much copper as an internal combustion engine.
All of this is good news for the sector, but when you combine these trends, you get a mixed picture. Ore grades are still declining, and the world will need even more copper than before. Its time, I think, to use the sustainability lens to think in more heretical ways about metals and how to build a circular economy. What if we rethink where we get metals fromnbsp i.e., why do we need to dig up new, or virgin, metals instead of reusing what weve already dug up
