Monel - Wikipedia

Monel 405 is the free-machining grade of alloy 400. The nickel, carbon, manganese, iron, silicon & copper percent remains the same as alloy 400, but the sulfur is changed from 0.024 max to 0.025-0.060%. Alloy 405 is used chiefly for automatic screw machine stock and is not generally recommended for other applications.

Five Common Myths about Portable XRF Analyzers in Mining

In this post, we'll examine some of the most common myths about portable XRF analyzers. Myth #1: XRF isn't effective for locating precious metals. In reality, precious metals can be detected directly by portable XRF analyzers in most instances, such as in ore grade control and exploration of rich zones.

Depending on the specific mineral liberation characteristics of the rougher and scavenger concentrates, these concentrates may be subjected to regrinding before upgrading in subsequent stages of cleaner flotation.

Cupronickel - Wikipedia

Cupronickel or copper-nickel (CuNi) is an alloy of copper that contains nickel and strengthening elements, such as iron and manganese. The copper content typically varies from 60 to 90 percent. (Monel metal is a nickel-copper alloy that contains a minimum of 52 percent nickel.) Despite its high copper content, cupronickel is silver in colour.

Analyzing Concentrated Ore Samples of Mo, Fe, and Cu with XRF

As I outlined in my last article about ore grade, mining geologists perform ore grade control to figure out where the most profitable ore bodies are in terms of location and mineral concentration variability.And field-portable x-ray fluorescence (FPXRF) is an effective analytical tool for high grade ore concentrates and grade control, especially when employing Empirical Mode.

Innovations: Introduction to Copper: Mining & Extraction

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.

Ore - Wikipedia

The cost of extraction must thus be weighed against the metal value contained in the rock to determine what ore can be processed and what ore is of too low a grade to be worth mining. Metal ores are generally oxides, sulfides, silicates, or native metals (such as native copper) that are not commonly concentrated in the Earth's crust, or noble ...
