Rio appears to be doing a pretty good job of controlling those costs, and there are new opportunities in terms of improving operational efficiency, including the first ore from the vital new Gudai-Darri mine. But it’s hard to shake off concerns that Australia’s big iron ore miners are facing worrying pressure, with falling demand and rising costs conspiring to stifle profitability. That’s important for investors – Rio’s shares fell 2.6 percent on Friday, picking up losses since their recent peak last month to 21 percent, while BHP fell 24 percent over the same period – but also for Australia’s state and federal governments, for which royalties and strong iron ore taxes have been a boon over the last few years. The supply side is not an issue here, given that large iron ore miners have strong cost discipline and keep volumes under control. But the demand picture is deteriorating as China’s economy continues to suffer. China’s economy is treading...

“Beauty is an iron mine,” says Australian mining magnate Gina Reinhart. He talked about a valuable resource, but iron is also very important for living organisms: from bacteria and fungi, to mammals like us. Shutterstock Iron acts as a key to various metabolic functions in our body. But iron deficiency remains one of the top global health risks recognized by the World Health Organization (WHO). ADVERTISEMENT CONTINUE READING BELOW Iron deficiency has become the most common micronutrient disorder worldwide, and COVID may exacerbate the problem. Iron is hard to come by The type of iron we mine is different from the biologically usable “free form” iron. Free-form iron has a tendency to jump between two chemical states, allows it to bind to various molecules, and participates in all sorts of important reactions in our bodies. But we see a different story again during the digestion of food. In our upper small intestine where iron is most effectively absorbed, free form iron tends to bin...

If you want to avoid feeling tired, making sure you include plenty of iron sources in your diet is very important. This is because iron is a vital mineral your body needs to make hemoglobin, a type of protein in red blood cells that carries oxygen from your lungs to the rest of your body. Without enough iron, we cannot make enough red blood cells to transport oxygen, leading to health problems and symptoms such as extreme fatigue. Women are more prone to iron deficiency anemia due to blood loss during periods, and may want to consider supplements as a result. There are also some adjustments you can make to your diet to aid absorption, such as taking iron with vitamin C sources. “Iron absorption is highly dependent on the health of the digestive tract,” adds Dr Margarita Kitova-John, a GP, functional medicine physician and founder Lantern Clinic (opens in a new tab) . “It starts in the stomach and mostly occurs in the small intestine. Adequate secretion of hydrochloric acid in ...
