Using wood powder as fuel in lime kilns, pilot case study

A Valmet white paper discusses the use of wood powder as a replacement lime kiln fuel, as well as the factors that must be considered when evaluating using wood powder as kiln fuel and the lessons learned from operating with wood powder. Södra has contributed to this paper based on their experience at Södra Värö mill with a wood powder firing system that was installed in 2014.

Controlling your flotation process

Flotation is an important part of mineral processing in most mining operations, requiring an accurate, durable, and repeatable level control valve to manage level control in the column, cell, staged reactor, or direct reactor. The head pressure to the control valve from each type of flotation process makes sizing a critical function to ensure proper operation of the valve and performance of the solution. For instance, flotation cells have very low driving head pressure to the valve. Since the head pressure is so low, inlet velocities, outlet velocities, and any bends or elbows in the piping can affect this low head pressure. If all factors are not considered carefully in this case, the danger is mis-sizing the level control valve on the low side.

Keeping your customer promise is the key to lasting customer relationships

While many factors play a role in building lasting customer relationships, serving the customer well and earning their trust will continue to be the most important aspect of a successful customer relationship. We interviewed our long-term but now retired Executive Team member, Jari Vähäpesola, to hear his insights and experiences about how to prove your worth and build commitment.

Information age calls for empathic leaders

In the era of rapid digitalization and emerging new technologies, one may think that they would be at the center of learning efforts. But no. Focus should instead be put on the leaders’ capacity for reflective leadership and on fostering empathy, humility and audacity.

Hydrogen is hard on valves

Under pressure, the hydrogen molecule H2 cracks metal and can even penetrate steel. Hydrogen fracture weakens the tensile strength and ductility of steel, which reduces its resistance to fracture and causes cracking.
