Vibrating Screen
For efficient wet or dry screening—Hi-capacity, 2-bearing design. Flywheel weights counterbalance eccentric shaft giving a “true-circle” motion to screen. Spring suspensions carry the weight. Bearings support only weight of shaft. Screen is free to “float” and follow positive screening motion without power-consuming friction losses. Saves up to 50% HP over 4- bearing types. Sizes 1 x […]
Can I use Seawater in my Greenhouse
How do Seawater Greenhouses Work? A seawater greenhouse is a type of greenhouse technology that utilizes seawater to grow crops in arid or desert regions. It combines two main elements: the greenhouse structure and the seawater desalination process. Here’s how a seawater greenhouse typically works: 1. Greenhouse Structure: The greenhouse is designed to provide a […]
What is the Role of Water in Lithium Mining
Balancing Resource Extraction and Water Sustainability Lithium, a key component in batteries that power electric vehicles and store renewable energy, has become increasingly vital in our pursuit of a sustainable future. As demand for lithium rises, so does the importance of understanding and addressing the environmental impact of its extraction. One critical aspect of lithium […]
Direct Lithium Extraction (DLE)
Direct Lithium Extraction (DLE) is an innovative method of extracting lithium from brine or other lithium-rich sources without the need for traditional evaporation ponds. Unlike conventional lithium extraction processes, which rely on the natural evaporation of water to concentrate lithium, DLE techniques offer a more efficient and environmentally friendly approach. The traditional lithium extraction process […]

Outcrops
In the examination of an undeveloped prospect a decision must be arrived at from an inspection of the outcrops and the exposures in a few shallow pits. Prospects that are offered for sale rarely expose any important quantity of good ore, work having usually been stopped when the immediate exploration no longer yielded favorable results. […]

Table of ContentsGenesis of a Typical Porphyry DepositNew CorneliaChuquicamataBraden Frequently the careful engineer puts the word porphyry in quotation marks or precedes it with “so-called,” when he writes of the Porphyry Copper mines. This is done by way of serving notice that he is aware that the term is not a precise one, though no […]
Metallurgy Problems
Table of ContentsParting LimitsAging While reflecting on the subject of my present paper, I soon realized that it would be very difficult to say something really new about any special aspects of metallurgy. In consideration of the excellent scientific work that has been done in the United States in connection with almost all the fundamental […]
