SX-EW (solvent extraction and electrowinning) | KGHM ...

SX-EW technology involves leaching (the process of dissolving useful ingredients with a solution) in atmospheric conditions of copper ore heaps by means of diluted sulphuric acid. Folowing leaching, the pregnant leaching solution is transported via a drainage system to the next stage. In an SX-EW reactor, the first process to take place is solvent extraction, which involves setting and ...

Solvent Extraction & Electrowinning (SX/EW) Plant Design

Cerro Verde began operations in April 1977, originally formed and operated by Minero Peru, as a state-run mining company. The electrowinning tankhouse was designed to produce 33,000 metric tonnes per year (mtpy) of copper cathode operating with current density of 184 amps per square meter (A/m2) and 88 percent (%) electrical current efficiency. In 1994 the mine was privatized and purchased by ...

Jameson cell - Wikipedia

Solvent extraction – electrowinning (often referred to as "SX–EW") is a process frequently applied for recovering copper from low-grade and/or oxidised copper ore. It involves leaching the copper from the ore using an acidic solution, collecting the leach liquor containing the copper and contacting this solution with an organic extractant.

Extractive Metallurgy of Copper | ScienceDirect

The SX process consists of extracting Cu 2+ from aqueous PLS into a copper specific organic extractant, separating the aqueous and organic phases by gravity, and then stripping Cu 2+ from the organic extractant into high-H 2 SO 4 electrolyte returned from the EW circuit. The process is continuous and is carried out in large Mixer-settlers.

Energy Use in US Steel Manufacturing - Stanford University

From the data in Table 1 and Fig. 3 it is apparent that the production of hot metal or pig iron is the most energy intensive process for steel production at roughly 13.5 × 10 9 joules per ton (1000 Kg) of pig iron produced. The basic oxygen furnace is the second most energy intensive process at 11 × 10 9 joules per ton or steel produced. The Electric arc furnace has significantly less energy ...
